My second project isn't dissimilar to yours- its a replacement for a
Medion PNA (i.e. built-in GPS, 3.5" touch screen, WinCE).  Both the
Pimoroni 4" screen that A Dumas suggests and the Adafruit 3.5" screen
would do my job, and probably yours too. The Pimoroni has much the best
resolution (800 x 480) compared with the Adafruit (480 x 320).

All RaspberryPi use Repbian, a port of Debian Linux, by default though
there are other OSen available.

I don't know how much Android has diverged since Linux was forked to
create it or what command shell or desktop manager it uses.
