64MB is pretty restricting for most things people would want to run on a Raspberry Pi, the text says you can run Debian on it but that feels like it would be pretty tight. That said, the thing is stupidly cheap for driving small displays (huh, it's analogue RGB though) with as a complete system, and the amount of GPIO available is quite incredible. I'll be excited to buy one to play with if the shipping doesn't double the cost.
