It's prettier. The glass and metal build is LUXURY. I'm NOT here for the plastic stuff the lesser phones are trying to peddle me.
The screen is so crisp. Pictures are beautiful and text is so CRISP.
The camera is perfect (better than the Droid X according to numerous reviews).
I have a Mac and it syncs with my phone perfectly. And it's an iPod. That's worth it's weight in gold.
However, the iPhone jailbroken is a whole different experience on it's own. Without it, iOS is a snooze.
However, some of the newer Android phones are tempting.
I couldn't have said it better....
