The Verge is reporting Microsoft is building its own gaming tablet. “The Xbox Surface will likely include a custom ARM processor and high-bandwidth RAM designed specifically for gaming tasks. We’re told these specifications could be altered to accommodate an unannounced Intel SoC and that the Xbox Surface is being developed independent of specific hardware architecture. Microsoft’s Xbox Surface won’t run a full version of Windows, rather this 7-inch tablet will run a custom Windows kernel. Messaging and other tablet functions may be supported, but the focus is on gaming.” Custom kernel. So, incompatible with Windows 8 and Windows Phone 8. Question. Why?
