It's really nothing fancy... just a mini-ITX computer jammed into a housing that looks a lot like the old Commodore 64.
The system uses a Dual core Atom Processor and Ion2 graphics, so while it will perform better than a netbook would running aces high, it still wouldn't play it 'well'.
*For the record my 9" netbook runs aces high at about 4-5 FPS with all options at minimum.
Prices run $250 for a barebones system (case/keyboard only, no internals)... to $595 for their cheapest complete system. I think their 'best' option is $900 which includes a blue-ray drive, 4GB of ram and a 1TB hard drive.
It also comes with Ubuntu Linux for now, however they will mail you their operating system (a version of Linux) along with their C64 emulating software as soon as it is available. While not included, you can install Windows on to it if you want.
