What I want to see in N9:

1. Resistive screen definitely. I want a stylus. Drawing is too fun.
2. Better Processor maybe 1 GHz with support for profiles with dynamic voltages and dynamic speed ie: At night you can set it to low voltage and low MHz for battery.
3. 4 Row Keyboard
4. Flash 10.1 + HTML 5 MicroB
5. Support for Portrait Mode ^_^
6. Less Trolls on the forums
7. Multitouch (It is possible on resistive screens)
8. More apps and games
9. USB Host Mode
10. Better Kickstand.

That's it. That's all that is missing from the N900. IMHO.
