Back in the day the Commodore 64 was THE computer. Only losers didn't have one. Problably the most successful pre-Mac/PC computer of all time, the Commodore 64 even to this day still has legions of crazy fan people who do stuff like write web browsers for it. Amazing.
Part of the reason it was so successful was for it's games, which were of about NES quality (which was advanced in the early 80's.) As time moved on and better systems came out C64s were repackaged and sold strictly as game consoles (finally accumulating in the ill fated Commodore 64 GS.)
So now with the craze in retrogamming-plug-and-play-TV thingys you can relive 30 of some of the better games from this era.
But the cool thing about this machine is that it's intended to be easily hackable to turn it into a full fledged Commodore 64 computer, capable of running any compatible software. Do a google and you can find directions for attaching a PC or PS2 keyboard, DIN connector for disk drive, etc.
Each unit is also PAL and NTSC compatible (since most of the homebrew stuff you'll find is PAL seeing the C64's following in Europe) and is based on a C64 Competition Pro Joystick.
Now, if all the other companies that make these TV Game-things would only follow Commodore's lead here and make thier stuff hackable (*cough ATARI cough*)
