Not really sure why they're branding it as a console when it's basically a portable Pi, and therefore far more versatile than "game console" implies. I suspect that will cause some confusion among potential customers who initially just see it as a game engine runtime.
One of the immutable laws of Raspberry Pi usage is that, for every application, a Pi will be either massively overpowered (this) or completely unnecessary (using them for "learning programming" when you have a perfectly good computer right there).
Truth, though I had to fight off the temptation to get one of those Elecrow Pi Laptops with a breadboard-type electronic kit inside. I don't think the RPi is overpowered for this - maybe for the stated purpose of emulating 8 bit games, but I like the idea of a general purpose computer that is not trying to be a tablet or TV.
