For me, it's probably the Widgets. Although the lack of them has forced a certain level of innovation. For example would Quick Calendar have bothered to make a notification shade option if they'd been able to make a widget instead? Weather bug developed a way to put the current temp in the notification bar, and when you pull the shade you can see today's current forcast for your location -- would they have tried if they had widget capability? There's something to be said for how programing limitations create opportunities for innovation. Other than the new look, can't really say I care about the other options. I probably won't like the virt keyboard, and autorotate will probably drive me nuts until I shut it off.
