Xbox Surface specs leak, detail a 7-inch tablet and powerful “stationary computing device”

Unlike most of the Microsoft-designed hardware (Zune, Kin, etc.), the Xbox is a strong seller, so this is potentially huge news – Xbox Surface, a 7″ tablet.

Is this the Microsoft-branded tablet that the rumor mill has been chatting about? Well, if it is, it sounds like a pretty odd design – besides the tablet, there’s also a “stationary computing device”, which is quite the powerhouse.
