Why I Need an iPad

I’m one of those who feel the iPad is the right tool for the job.

This is mostly meant as a reply to this blogthread. But it’s also more generally about my personal reaction to Apple’s iPad announcement.

Some background.

I’m an ethnographer and a teacher. I read a fair deal, write a lot of notes, and work in a variety of contexts. These days, I tend to spend a good amount of time in cafés and other public places where I like to work without being too isolated. I also commute using public transit, listen to lots of podcast, and create my own. I’m also very aural.

I’ve used a number of PDAs, over the years, from a Newton MessagePad 130 (1997) to a variety of PalmOS devices (until 2008). In fact, some people readily associated me with PDA use.

As soon as I learnt about the iPod touch, I needed one. As soon as I’ve heard about the SafariPad, I wanted one. I’ve been an intense ‘touch user since the iPhone OS 2.0 release and I’m a happy camper.

(A major reason I never bought an iPhone, apart from price, is that it requires a contract.)

In my experience, the ‘touch is the most appropriate device for all sorts of activities which are either part of an other activity (reading during a commute) or are simply too short in duration to constitute an actual “computer session.” You don’t “sit down to work at your ‘touch” the way you might sit in front of a laptop or desktop screen. This works great for “looking up stufff” or “checking email.” It also makes a lot of sense during commutes in crowded buses or metros.

In those cases, the iPod touch is almost ideal. Ubiquitous access to Internet would be nice, but that’s not a deal-breaker. Alternative text-input methods would help in some cases, but I do end up being about as fast on my ‘touch as I was with Graffiti on PalmOS.

For other tasks, I have a Mac mini. Sure, it’s limited. But it does the job. In fact, I have no intention of switching for another desktop and I even have an eMachines collecting dust (it’s too noisy to make a good server).

What I miss, though, is a laptop. I used an iBook G3 for several years and loved it. For a little while later, I was able to share a MacBook with somebody else and it was a wonderful experience. I even got to play with the OLPC XO for a few weeks. That one was not so pleasant an experience but it did give me a taste for netbooks. And it made me think about other types of iPhone-like devices. Especially in educational contexts. (As I mentioned, I’m a teacher)

I’ve been laptop-less for a while, now. And though my ‘touch replaces it in many contexts, there are still times when I’d really need a laptop. And these have to do with what I might call “mobile sessions.”

For instance: liveblogging a conference or meeting. I’ve used my ‘touch for this very purpose on a good number of occasions. But it gets rather uncomfortable, after a while, and it’s not very fast. A laptop is better for this, with a keyboard and a larger form factor. But the iPad will be even better because of lower risks of RSI. A related example: just imagine TweetDeck on iPad.

Possibly my favourite example of a context in which the iPad will be ideal: presentations. Even before learning about the prospect of getting iWork on a tablet, presentations were a context in which I really missed a laptop.

Sure, in most cases, these days, there’s a computer (usually a desktop running XP) hooked to a projector. You just need to download your presentation file from Slideshare, show it from Prezi, or transfer it through USB. No biggie.

But it’s not the extra steps which change everything. It’s the uncertainty. Even if it’s often unfounded, I usually get worried that something might just not work, along the way. The slides might not show the same way as you see it because something is missing on that computer or that computer is simply using a different version of the presentation software. In fact, that software is typically Microsoft PowerPoint which, while convenient, fits much less in my workflow than does Apple Keynote.

The other big thing about presentations is the “presenter mode,” allowing you to get more content than (or different content from) what the audience sees. In most contexts where I’ve used someone else’s computer to do a presentation, the projector was mirroring the computer’s screen, not using it as a different space. PowerPoint has this convenient “presenter view” but very rarely did I see it as an available option on “the computer in the room.” I wish I could use my ‘touch to drive presentations, which I could do if I installed software on that “computer in the room.” But it’s not something that is likely to happen, in most cases.

A MacBook solves all of these problems. and it’s an obvious use for laptops. But how, then, is the iPad better? Basically because of interface. Switching slides on a laptop isn’t hard, but it’s more awkward than we realize. Even before watching the demo of Keynote on the iPad, I could simply imagine the actual pleasure of flipping through slides using a touch interface. The fit is “natural.”

I sincerely think that Keynote on the iPad will change a number of things, for me. Including the way I teach.

Then, there’s reading.

Now, I’m not one of those people who just can’t read on a computer screen. In fact, I even grade assignments directly from the screen. But I must admit that online reading hasn’t been ideal, for me. I’ve read full books as PDF files or dedicated formats on PalmOS, but it wasn’t so much fun, in terms of the reading process. And I’ve used my ‘touch to read things through Stanza or ReadItLater. But it doesn’t work so well for longer reading sessions. Even in terms of holding the ‘touch, it’s not so obvious. And, what’s funny, even a laptop isn’t that ideal, for me, as a reading device. In a sense, this is when the keyboard “gets in the way.”

Sure, I could get a Kindle. I’m not a big fan of dedicated devices and, at least on paper, I find the Kindle a bit limited for my needs. Especially in terms of sources. I’d like to be able to use documents in a variety of formats and put them in a reading list, for extended reading sessions. No, not “curled up in bed.” But maybe lying down in a sofa without external lighting. Given my experience with the ‘touch, the iPad is very likely the ideal device for this.

Then, there’s the overall “multi-touch device” thing. People have already been quite creative with the small touchscreen on iPhones and ‘touches, I can just imagine what may be done with a larger screen. Lots has been said about differences in “screen real estate” in laptop or desktop screens. We all know it can make a big difference in terms of what you can display at the same time. In some cases, two screens isn’t even a luxury, for instance when you code and display a page at the same time (LaTeX, CSS…). Certainly, the same qualitative difference applies to multitouch devices. Probably even more so, since the display is also used for input. What Han found missing in the iPhone’s multitouch was the ability to use both hands. With the iPad, Han’s vision is finding its space.

Oh, sure, the iPad is very restricted. For instance, it’s easy to imagine how much more useful it’d be if it did support multitasking with third-party apps. And a front-facing camera is something I was expecting in the first iPhone. It would just make so much sense that a friend seems very disappointed by this lack of videoconferencing potential. But we’re probably talking about predetermined expectations, here. We’re comparing the iPad with something we had in mind.

Then, there’s the issue of the competition. Tablets have been released and some multitouch tablets have recently been announced. What makes the iPad better than these? Well, we could all get in the same OS wars as have been happening with laptops and desktops. In my case, the investment in applications, files, and expertise that I have made in a Mac ecosystem rendered my XP years relatively uncomfortable and me appreciate returning to the Mac. My iPod touch fits right in that context. Oh, sure, I could use it with a Windows machine, which is in fact what I did for the first several months. But the relationship between the iPhone OS and Mac OS X is such that using devices in those two systems is much more efficient, in terms of my own workflow, than I could get while using XP and iPhone OS. There are some technical dimensions to this, such as the integration between iCal and the iPhone OS Calendar, or even the filesystem. But I’m actually thinking more about the cognitive dimensions of recognizing some of the same interface elements. “Look and feel” isn’t just about shiny and “purty.” It’s about interactions between a human brain, a complex sensorimotor apparatus, and a machine. Things go more quickly when you don’t have to think too much about where some tools are, as you’re working.

So my reasons for wanting an iPad aren’t about being dazzled by a revolutionary device. They are about the right tool for the job.


Speculating on Apple’s Touch Strategy

This is mere speculation on my part, based on some rumours.

I’m quite sure that Apple will come up with a video-enabled iPod touch on September 9, along with iTunes 9 (which should have a few new “social networking” features). This part is pretty clear from most rumour sites.

AppleInsider | Sources: Apple to unveil new iPod lineup on September 9.

Progressively, Apple will be adopting a new approach to marketing its touch devices. Away from the “poorperson’s iPhone” and into the “tiny but capable computer” domain. Because the 9/9 event is supposed to be about music, one might guess that there will be a cool new feature or two relating to music. Maybe lyrics display, karaoke mode, or whatever else. Something which will simultaneously be added to the iPhone but would remind people that the iPod touch is part of the iPod family. Apple has already been marketing the iPod touch as a gaming platform, so it’s not a radical shift. But I’d say the strategy is to make Apple’s touch devices increasingly more attractive, without cannibalizing sales in the MacBook family.

Now, I really don’t expect Apple to even announce the so-called “Tablet Mac” in September. I’m not even that convinced that the other devices Apple is preparing for expansion of its touch devices lineup will be that close to the “tablet” idea. But it seems rather clear, to me, that Apple should eventually come up with other devices in this category. Many rumours point to the same basic notion, that Apple is getting something together which will have a bigger touchscreen than the iPhone or iPod touch. But it’s hard to tell how this device will fit, in the grand scheme of things.

It’s rather obvious that it won’t be a rebirth of the eMate the same way that the iPod touch wasn’t a rebirth of the MessagePad. But it would make some sense for Apple to target some educational/learning markets, again, with an easy-to-use device. And I’m not just saying this because the rumoured “Tablet Mac” makes me think about the XOXO. Besides, the iPod touch is already being marketed to educational markets through the yearly “Back to school” program which (surprise!) ends on the day before the September press conference.

I’ve been using an iPod touch (1st Generation) for more than a year, now, and I’ve been loving almost every minute of it. Most of the time, I don’t feel the need for a laptop, though I occasionally wish I could buy a cheap one, just for some longer writing sessions in cafés. In fact, a friend recently posted information about some Dell Latitude D600 laptops going for a very low price. That’d be enough for me at this point. Really, my iPod touch suffices for a lot of things.

Sadly, my iPod touch seems to have died, recently, after catching some moisture. If I can’t revive it and if the 2nd Generation iPod touch I bought through Kijiji never materializes, I might end up buying a 3rd Generation iPod touch on September 9, right before I start teaching again. If I can get my hands on a working iPod touch at a good price before that, I may save the money in preparation for an early 2010 release of a new touch device from Apple.

Not that I’m not looking at alternatives. But I’d rather use a device which shares enough with the iPod touch that I could migrate easily, synchronize with iTunes, and keep what I got from the App Store.

There’s a number of things I’d like to get from a new touch device. First among them is a better text entry/input method. Some of the others could be third-party apps and services. For instance, a full-featured sharing app. Or true podcast synchronization with media annotation support (à la Revver or Soundcloud). Or an elaborate, fully-integrated logbook with timestamps, Twitter support, and outlining. Or even a high-quality reference/bibliography manager (think RefWorks/Zotero/Endnote). But getting text into such a device without a hardware keyboard is the main challenge. I keep thinking about all sorts of methods, including MessagEase and Dasher as well as continuous speech recognition (dictation). Apple’s surely thinking about those issues. After all, they have some handwriting recognition systems that they aren’t really putting to any significant use.

Something else which would be quite useful is support for videoconferencing. Before the iPhone came out, I thought Apple may be coming out with iChat Mobile. Though a friend announced the iPhone to me by making reference to this, the position of the camera at the back of the device and the fact that the original iPhone’s camera only supported still pictures (with the official firmware) made this dream die out, for me. But a “Tablet Mac” with an iSight-like camera and some form of iChat would make a lot of sense, as a communication device. Especially since iChat already supports such things as screen-sharing and slides. Besides, if Apple does indeed move in the direction of some social networking features, a touch device with an expanded Address Book could take a whole new dimension through just a few small tweaks.

This last part I’m not so optimistic about. Apple may know that social networking is important, at this point in the game, but it seems to approach it with about the same heart as it approached online services with eWorld, .Mac, and MobileMe. Of course, they have the tools needed to make online services work in a “social networking” context. But it’s possible that their vision is clouded by their corporate culture and some remnants of the NIH problem.

Ah, well…


Patent Filing the Future of Instructional Podcasts

Glad to see Apple thinking about some new ways to produce and distribute podcasts.

AppleInsider | Apple filing takes Podcasts to the next level

It’s quite possible that this patent filing may not lead to anything concrete but the very fact that Apple devotes some time to the issue could lead to interesting things. In fact, other manufacturers may be motivated to move in this space and this might have powerful effects on educational technology.


iRiver H120 (Digital Audio Jukebox)

Recently purchased a brand new iRiver H120 with remote control on eBay from OutletMP3. Paid 132.50$ plus 18$ shipping. Also purchased a 3-year warranty through SquareTrade for 16$.
Item arrived as described, with both the European power adapter (in the original box) and a North American power adapter (in the shipping box). The remote control is included in the package but is outside of the original box. OutletMP3 sells those iRiver H120 devices with or without remote control (usually at about the same price).
Yes. “Would do business with OutletMP3 again.” (As it turns out, they sell iriver products quite frequently on eBay and they have an eBay store with “Buy It Now” iRiver H120 devices without remote for 150$ each.)
The best things about this device are its recording features. Those iRiver H1x0 models can record uncompressed sound in WAV format at 16bit with a sampling rate of 48 kHz (so-called “DAT quality”), 44.1 kHz (so-called “CD-quality”), or lower (“FM-quality,” “voice quality”). It also records directly to MP3 files (with the official firmware) in a variety of encoding settings (up to 320 kbps). It has an internal microphone for voice dictation as well as an input for external microphone, analog line in, or optical in.
The box includes a surprisingly decent lavaliere-style monophonic microphone. Not an excellent microphone in any way but clearly better than one might expect (though Laith Ulaby had told me that this microphone was decent).

In terms of operation, the unit has some strengths. The overall interface is much less convenient than that of the iPod, say, but the battery lasts longer than most iPods (for playback). The iRiver H120’s remote has a small LCD screen which shows enough information for most needs making it possible for me to keep the H120 in my pant pocket and operate the device with the remote. While, among portable players, only the iPod has native support for AAC and lossless formats, iRiver players support Ogg Vorbis and WMA. Haven’t done anything in Ogg format yet but it might be an interesting option (though it does make files less compatible with other players).

Apart from navigation and interface, the main differences with my previous iPod 2G have to do with iTunes integration. The iPod‘s synchronization with iTunes made it rather convenient to create and update playlists or to transfer podcasts. iRiver’s models may not be used in the same fashion. However, the iRiver H120 can in fact be used with iTunes through a plugin meant for Archos players. However, this plugin seems to have some problems with a few files (probably because of invalid characters like ‘/’ and ‘:’ in filenames), generates non-working playlists on Mac OS X, and puts all filed in an “Artist/Album” hierarchy which makes iRiver navigation more complicated.

What surprised me somewhat was that the H120, a USB 2.0 device, works perfectly well with my old iBook (Dual USB) which only has USB 1.1 ports. No need for special drivers and the device then works pretty much like a (20GB) USB drive. Since the iRiver H120 works as a USB drive, it’s easy to transfer files to and from the device (contrary to the iPod which makes somewhat more difficult). All audio files can be put at the root level on the iRiver and audio recordings made on the iRiver are in the “RECORD” folder at the root level of the drive. While the iBook’s USB 1.1 ports are much slower than USB 2.0 ones, they do the job well enough for my needs. (Will be going back to my entry-level emachines H3070 in a few days.) A 400 MB file recorded on the iRiver (about 40 minutes of 16 bit stereo sound at 44.1 kHz) transferred to the iBook through USB 1.1 in less than ten minutes. Slow, but bearable. My old iPod used a Firewire 400 (aka IEEE 1394 or i.Link) connection which is about the same speed as USB 2.0 in most conditions. My entry-level emachines desktop has both USB 2.0 and Firewire 400 ports (thanks to an inexpensive Firewire card).

Was thinking about putting Rockbox on the H120 but SquareTrade tells me that it may void their warranty, which would be an inconvenient. The Rockbox has some neat features and seems safe enough to use on “production machines,” but its features aren’t that compelling for me at this point.
The H120 has a radio (FM) tuner, which could be useful to some people but isn’t really a compelling feature for me. Haven’t listen to much radio in the past several years. Podcasts are soooo much better!

Speaking of podcasts… One of my reasons for purchasing this machine (instead of a more recent iPod) was the ease of recording. This is clearly not a professional recording device but the sound quality seems quite decent for my needs at this point. Should be using it to record lectures and distribute them as podcasts or “lecturecasts” (yeah, ugly name, sorry!). In my mind, educational podcasting can supplement lectures quite nicely. Have been to a few workshops and presentations on technology use in teaching and most people seem to agree that technology is no replacement for good pedagogy but that good pedagogy can be supplemented and complemented (if not complimented!) by interesting tools. Had been thinking about a recording iPod to integrate podcasts with course material. It would have been quite useful, especially in connection with iLife and iWork. But an iPod 5G (with video) is already much more expensive than my iRiver H120 and the add-ons to enable 44.1 kHz / 16 bit recording on the iPod are only now getting to market at a price almost half that of my brand new iRiver H120. Plus, though the iPod is well-integrated with iTunes on Windows, iLife and iWork applications are only available on Mac OS X 10.4 and, thus, will not run on the entry-level emachines H3070 which will become my primary machine again in a few days.
In other words, my ideal podcasting/lecturecasting solution is out of my reach at this point. And contrary to tenure-track faculty, lecturers and adjunct faculty get no technology budget for their own use.
Ah, well…

Still, my iRiver H120 will work fine as a recorder. Already did a few essays with voice and environmental sounds. The lavaliere microphone was quite convenient to record myself while taking a walk which sounds like an unusual activity but was in fact quite relaxing and rather pleasant. In terms of environmental sounds, the same microphone picked up a number of bird songs (as well as fan noises).
Among the things that distinguish the H120 from a professional recorder is the lack of a proper calibration mechanism. It’s not possible to adjust the recording levels of the two channels independently and it’s even not possible to adjust volume during recording. (There’s a guide offering some guidance on how to work within those constraints.) Quite unsurprisingly (for what is mostly an MP3 player) but also making the device less of a professional device, its jacks are 3.5 mm “stereo mini-plugs” (instead of, say, XLR jacks). For that matter, the iRiver H120 compares favourably to several comparably-priced MiniDisc recorders, even Hi-MD models. Did field research with a used ATRAC 4.0 MiniDisc recorder. That setup worked somewhat adequately but this iRiver H120 is much of an improvement for me.

Got a few pet peeves about the iRiver H120. For instance, it has no actual clock so recorded files do not carry a timestamp. A minor quibble, of course, but it would have been useful. The overall navigation is as awkward as that of my first MP3 device, the RioVolt (which also used iRiver firmware). One navigational issue is that navigating up and down in the folder hierarchy is done through the stop and play buttons instead of, say, using one of the three jog switches on the remote. Some functions only work when the device is stopped while others work while it’s playing. Switching from hard-disk playing to recording or to FM is a bit awkward and cumbersome. The unit takes a while to turn on and doesn’t really have a convenient sleep mode. While it is possible to resume playing on a track that has been stopped, this feature seems not to work every time. Fast forwarding rate (“scan speed”) is set in a menu instead of being dynamic as on the iPod. The device doesn’t support ratings or, really, descriptions (although Rockbox might be able to support those).

Also got a few well-appreciated features, apart from those stated above. The EQ and SRS presets are appropriate and relatively easy to use. Contrary to the iPod 2G it is possible to play files at a higher rate (increasing the “playback speed”) making it possible to listen to voice at a higher speech rate (and higher frequency). It’s also possible to delete files directly from the device.

At any rate, that’s already a long entry and experience with my H120 will probably push me to write more about the device.

Feel free to comment or send questions through email.


Lecturecasts (Podcast Lectures, Lecture Podcasts)

UPDATE: Purchased an iRiver H120 jukebox/recorder.

Was commenting on Tama Leaver‘s post about watching his own lecture videos on a fifth-generation iPod. There’s a lot of room for experimentation with these methods and technologies.

Apple is well-positioned in this sphere, actually. Its iLife and iWork suites can integrate content in different formats, some of which might actually work on the iPod (Keynote to Quicktime H.264, GarageBand to AAC enhanced podcast). Furthermore, Apple has this iTunes U project for hosted and protected podcast content. Not to mention the obvious point about Apple’s iPod success. Don’t have the necessary material to try it out but it should be relatively simple to create full-featured lecture podcasts using these tools. In fact, there’s already a product out meant to simply this integration (can’t try it out myself, unfortunately).
With at least three microphones for iPod 5G coming out Real Soon Now (XtremeMac’s MicroMemo, Belkin’s TuneTalk, and Griffin’s iTalkPro), life can become quite fun indeed for those of us who’d like to “lecturecast.” It’s an even better time to turn to academic podcasting with so many podcasting projects springing up at such diverse institutions as IUSB, Duke, UdeM, Brandeis, and IUB. The open-source course management system Moodle now supports podcasts. So does Sakai, the free/open knowledge management project. Of course, educational podcasting isn’t new. But it’s gaining steam.
