A handheld Amiga 1200 clone with a 320x200 lcd display, and a small HDD (a few gigs) which is able to boot and play games from ADFs, utilising the thousand games which are out: the old software base in a new wrapping. Having an USB connector, probably with TV out, builtin CD32 joypad and infrared/bluetooth multiplayer options (emulating the second joyport this way).
Now that would be nice for a competitive price.
My 2 eurocents :-)
