Minus the app store  Palm's  Pre phone looks like it has everything ,  obviously  I can't  play with it  to see if it's as   smooth as the demo but it  beats up the iPhone in many important ways. The app store , the Facebook apps,  the  Android ,Blackberry and jesus  will it ever end?  Remember I love this stuff and it's a chore for me.


Multi tasking between  screens
Removable battery. 
Option of a real keyboard
Easy to develop for (  in theory- business rules are  usually the biggest hurdle)

While the former can be coded into the iPhone  Apple's reticence to give  basic features like cut and paste between apps, heck even on the same page, reduces it to an information in most cases. That's not a given though the hardware should be able to drive it  but I think their battery issues really prvent this from ever becoming a useful multitasker in it's current inception though I'd still like that to be a choice.
