Nexus 1 is a bad move in my opinion, Uses a dodgy method of Resolution which actually makes it quite poor in my books. If your going for the N1 go with the HTC which is essentially the SAME phone but with better support (can't remember the name).

I believe the Droid also has been OC'ed to around 900-1000 but don't quote me on that.

I chose the N900 because of its potential, Meego could be on the cards soon and overall its the real geeks device
