HowardChui.com has a review of a prototype Nokia N91 up. It's the most comprehensive to date, and confirms the following things (as far as anything can be confirmed by a review of a prototype):
1. It has a metal shell.
2. The media keys work to operate the music controls at all times.
3. There is a 3.5mm port, and a remote control attachment which has a microphone built it. (And usage is therefore probably similar to the SE w800i with it's remote.)
4. It's freaking heavy.
5. Wifi was present but "not fully functional"
6.The music functionality seems to work well, even in the prototype.
Yums. Nokia! Send me a production N91 to review!
