Like many warm-blooded geeks, I've been thinking about the iPhone for the past week since Apple announced it. I'm kind of cool on it (more on the that later) but I'm happy people are thinking and talking about mobile, since I am obsessed with the mobile application space and I'm always happy to sit in the corner add my kibitz to the chatter.
There is a lot of negative buzz surrounding developers not being allowed to install applications on the iPhone, which I believe is a red herring. Developers won't be allowed to install applications, but they will be allowed to install widgets, which is just as good. Hit F12 - that's what your iPhone "dock" will look like. I've got stocks, a nice Flickr slideshow, a Vox widget, Magnolia bookmarks, package and flight tracking, and much more. It's far more useful (and beautiful) than the applications shipped with any phone today. Webkit runs greeat right now on my Nokia N731, and since it's the same webkit2, I'm sure it will run great on the iPhone.
I'll probably hold off on the iPhone for a while, since unlike Matt Haughey, I love my phone. Actually I should say "phones," since I have two: a "home" mobile (the aforementioned N73) and a "work" mobile, a Treo 700p. I love them both. The Nokia N73 has a 3+ megapixel camera, and I basically use it as a Vox appliance. Since the Vox mobile application sits at such a low level on the phone, it certainly won't work on the iPhone, which will certainly feature similarly deep iLife and .Mac integration (as it should). The Treo is basically a voice, email and calendaring appliance, and it's nearly perfect for that. Plus, it runs on Sprint's 3G network, which is lightning fast in the city.
Having said that, syncing is still the great unsolved problem for phones. It's very telling that Apple is using iTunes to sync instead of iSync, and what that basically says to me is that iSync is actually never going to get better. The Missing Sync is actually really good at syncing photos (pictures go right from the treo to iPhoto). For PC users, Lifeblog is very good at syncing pictures and text messages into a nice timeline, but it doesn't work under OS X. If Apple really, really nails this, and unifies the address book, voicemail, text messaging, picture messaging and email into a single stream that is nicely indexable and sortable, that will be a product worth looking at. But I doubt Apple will get this right, because iSync is still terrible.
1 Disclaimer: I have done some work for Nokia in the past, specifically on the Lifeblog project, and I had a wee bit of input on the way this stuff works. If not real input, at least an influence of an occasional thought by people who have real input.
