 these can be done as internal USB devices.

 there's one on the CPU Card - a 2nd one would need to be a USB device.

 not yet.

 well there's that SDR Radio IC from Realtek, which people are
beginning to explore using GNURadio.  it could well be used for GPS as
well as FM - just not both at the same time. RTL2832U+e4000 are the
two ICs needed.

 if it runs on OpenGL ES 2 it should be possible.

 depends significantly on whether it's resistive or touch screen, and
on whether the screen is 800x480, 800x600 or 1024x600.

 capacitive screens are *more* expensive than the LCD panels behind
them.  7in 800x600 LCDs are roughly.... $15 in 10k volumes; capacitive
screens last time i checked were more like $50 (!) but the prices will
almost certainly have come down by now.

 resistive overlays by contrast are under $5.

 no problem.

 work out the screen size and the touchpanel type, ok?
