Given that Android has just overtaken iPhoneOS in market share (in the US at least), why doesn't Google code an n900 build? Given it's similarity to the Droid it shouldn't be much trouble (with respect to the great efforts made here) and would add another Android device to their list.

Saying that, I'm not as naive as I'm sounding - obviously the small issue of the n900 being a Nokia device has something to do with it. Just dreaming really...
