Scroll wheel and buttons. I use the scroll wheel constantly, and the buttons are pretty valuable. Having instant access to the messaging and web browser is pretty useful, having a button mapped for the flashlight and one for the camera, and having the easily-accessible OK button where my thumb is anyway. Also kind of miss the external microSD slot. Still, as has been said, I think it's worth it for having over four times the RAM alone, not to mention the other stuff.

Oh, and my extended battery. I'm not going to enjoy having to wait three or four months again for Seidio to make a decent battery for it that I'll have to buy a new holster for.
