A while back, Fez developers Polytron released a shirt featuring a not-real gaming handheld called the Polytron Portable Pro. It's now been upgraded to two newer, more contemporary ideas for a not-real handheld.
Apparently inspired by Teenage Engineering's OP-1 synthesizer+, but looking just as much like a Speak-and-Spell, I'd buy one in a heartbeat.
No idea what I'd do on it, what with all those buttons, but in case you couldn't already tell, functionality seems to be taking a backseat here to eyecandy.
