One very important advantage is that Android is a multitasking OS (i.e. apps can run in the background - not only one at a time as on iPhone)And almost everything can be changed/altered by downloading apps. If you don't like the SMS-application or call-manager or whatever, it can be exchanged by another app developed by someone else. Apple does not allow this. It can be a bit sluggish sometimes when you've been running a heavy app for a while and exit to home screen again, and that's a consequence of the real multitasking OS, but it's not very bad at all... And well worth the ability to run apps in the background.[/citation]
The iPhone's 3.0 OS can run apps in the background, although running 3.0 on any model other than the 3GS is apperently horrifyingly slow.
