The postmonster ate my post. Summary of thoughts after watching keynote:
iPhone lack of SDK is even worse than I'd assumed. One literally launches Safari and goes to a bookmark. Their demo app is a a phonebook which literally does a round trip to the server for every step. That'll be fun over edge, especially when downloading the bitmaps to make buttons look like an iPhone app. It'll be even more useful when you travel outside the coverage area. The "no SDK needed" is a huge insult to all the developers who paid $$$ to be there to watch that go down. At least they didn't cheer.
The transparent menu bar is ugly. I don't understand who thought that would be a good idea. The dock seemed silly, but I'm undecided. They really should move it to the side by default, they're only selling widescreen displays these days.
Coverflow will impact battery life. The demands on the video card are one thing, but the demands on the hard drive are going to be much more. One can extrapolate from the 64 bit demo that the mac Steve was using had well over 8GB of memory. And you're gonna need it.
