The netbook mix is specially compiled for X86 processors so it will not work with the N900 if not modified.

The resolution of the screen of the N900 would not result any problems but the UI is designed to be used with a mouse. I would like an UI to be used more efficiently.

I believe IF there will be MeeGo for N900, the User Interface/theme will be similiar to the one you saw. Just don´t get your hopes up too much about that...
