I can't wait for some manuals. The pix show what appear to be an IR emitter
and IR receiver and there are 20 I/O pins. If these are accessible for
programming, adding RF should be easy.

It appears they intend the 1MB flash to store screen images that can be
preloaded via RS232 or USB. The controller limits it to 256 colors but
that's probably sufficient for command & control applications.

This link gives a few more details.

There is a manual available for the non-touchscreen version. It looks like
it uses the SiliconLabs single chip RS232/USB bridge. I've used that in a
couple of prototypes.

It would be superb if the ATMega128 can be user programmed.

I also noticed the future, smaller ezLCD-003 $50 touchscreen. It's 65K
colors.
