Errr... You do know that Ubuntu supports gnome, kde, lxde, xfce, and probably some other desktop enviroments, right? Anyways...

This is being typed from a docked Atrix, overclocked to 1500 Mhz, running LXDE, and, especially considering that suckorola has decided to dump the Webtop Ubuntu enviroment, opting instead to create a lame Tablet UI for the docks, I think I've just found my next phone.

Btw, personally I consider the Atrix to be the spiritual successor to the N900. Hell, motorola even made the same mistake nokia did and ignored they had gold on their hands with the full desktop on phone with dock concept.
