And to bring the thread back a bit to other WWDC news, it looks like the iPhone will finally be able to access files on an iDisk officially. Several various 3rd party programs have existed to do similar, however the Apple one will also allow easy e-mailing of any file on the disk to someone, by moving it into a public section of the iDisk and e-mailing a URL. Still not quite as nice as just exposing the file system and allowing files to be synced, but handy nonetheless.

Also, for anyone with 3.0 and MobileMe, Locate my iPhone is up and running now. I'll hopefully never lose my phone, but it's good to know I have a chance at recovering it now. I'm betting a similar feature shows up for future Mac laptops, as 10.6 has Core Location built in and uses it to set the time zone automatically.
