Please, pretty please ...
I know you have been inspired by the RPi but please:- don't make the same huge mistake that they did by releasing ARM hardware without Android O/S support.
(And if possible, please include in your Android version an option to use any cheaply-available WiFi stick as current Android releases tend to be made for one and only one WiFi chip that severely limits the choice for developer boards. Not a showstopper 'tho.)
Put another way how cool would it be to announce the worlds' first Android supercomputer?
PS - love that spell checker!
