Yeah, just put in everything you can for abou 600 € and ill buy it.
N900 is great. A redesigned N900 may be better if nokia doesnt loose any features (like the HW Keyboard and the Stylus (i know, its not the latest fashion to use this, but it realy allows good browsing experience and stuff)
The next device should have a native USB-Host. But thats all i miss.

Edit: Who is responsible for this nice Tags crushing my wet dreams?
