This is some very cheap computing power! It comes with the operating system: Ubuntu Linux 12.10, however if you want Windows and had a spare licence it should work very well on this hardware, or you can add Windows 7 to the price, but out of the box with Ubuntu it should be very good at less than $200 for a laptop:
