This.  I want more control over the phone.  I want to know when the cell 
modem, microphone and camera are shut down.  If I don't have the 
documentation (including pcb layout and source code), I can't make 
certain that it is under my control.

Other than that, I want Linux in a small form factor with a touchscreen, 
wifi and cell modem.
