Possible? If the chips fit in that form factor. Likely? I think it would be quite difficult outside of a real company. I have a list of components drawn up using bluetooth, but seriously Nokia missed the boat not having a magnetometer on board. I sure hope the n900's can run android because some of the "gee whiz" apps they seem to be looking for won't run on the n900. I'm questioning why I'm willing to bend over backwards to add it, especially if a 800x480+ android phone comes out.
