As everyone are asking for different form factor devices and everyone wants something different. Why not take the TOH idea a little bit further. Check the C.H.I.P. (there is even thread on TMO) and the PocketC.H.I.P. Basically you can have some "soul" part (like chip) that can be connected into different HW (see it as PocketC.H.I.P.) and everyone gets what he wants with single board and various extensions(to netbook, tablet, phone and etc).
