Head to Head: iPhone vs. Android - PCWorld
For the record, I've had the Droid Incredible since the day it came out and it is a great phone, other than the battery issues. I use custom Launchers because of the speed increase, although it sucks I have to give up my Sense widgets.
There are so many 'features' I could simply never give up for the current version of iPhone/iOS. You are simply giving up way too much in functionality for what you get in style/looks/intuitiveness.
I really, really like iPhones, especially the hardware, the beauty and capacitive precision of the screen, and way multimedia is setup. But I'm baffled how apple can't come up with a better notification system, widgets, better search, and the ability to customize more. The notification system and the desktop screens/launcher are reasons alone why I just could not make the switch to iPhone as it stands now.
