iTunes is overloaded.
iTunes first came out in 2001. At the time, you could use it to rip CDs, burn CDs, play ripped files, and organize those files. You could also use it to copy files to an MP3 player (the iPod didn’t exist at that time).
The personal computing landscape has changed a lot since then, and so has iTunes. It’s being called on to do a lot more.
I’ve said before that the Mac works best when you “drink Apple’s kool-aid,” that is, organize your contacts in Apple’s address book, your appointments in iCal, etc, because these apps act as a front-end to databases that other apps can easily tap into. The same goes for iTunes: Apple nudges you into using it to organize not only your music, but also your video files, and the iTunes database becomes almost like a parallel file system for media files. iPhoto is the manager for, well, photos.
When I first got an iPod a couple years ago, it seemed a bit odd that I could sync my contacts and calendars to itâ€”through iTunes. While it makes sense to manage one’s iPod through iTunes, there was already a subliminal itch of cognitive dissonance.
With the iPhone, that cognitive dissonance is breaking out into a visible rash. The media types that it manages now includes applications for the iPhone. iPhoto is the mechanism for selecting photos to copy to the iPhone, and either it or Image Capture is used to download photos taken with the iPhone’s camera. Curiously, there’s no way to get photos off the iPhone within iTunes; this feels like an oversight, or perhaps someone in Apple was feeling a bit of that itch as well, and felt unwilling to load up iTunes with another function even further from its central purpose.
While I’m not aware of any yet, at some point there will be apps from independent developers that need to exchange files between the desktop and the iPhone other than those handled by iTunesâ€”it’s easy to imagine word-processing files, PDFs, presentation decks, etc, being copied back and forth. It’s not clear how that will happen. It could all happen via the Internet, although that would be indirect both physically and in terms of the user’s experience. For large files, it would be annoying, and for people without unlimited-data plans, potentially expensive. Apple does offer programmers a bundle of functions called “sync services,” but this requires the desktop application be written to support syncing in the first place. For a lot of the file transfers I envision, syncing wouldn’t be the appropriate mechanism. There’s not even a way to get plain text files from Apple’s own Notes app off the iPhone. It’s widely speculated that cut and paste are absent from the iPhone because Apple hasn’t figured out a good interface for it. I suspect it’s the same thing here: they haven’t figured out a good, general mechanism for moving files between iPhone and desktop.
At some point, Apple is going to have to re-think the division of labor in its marquee apps, to separate organizing files from manipulating or playing them.
