The FCC has today revealed previously confidential document submitted by Microsoft.
The documents describe a Tablet Computer running the Windows RT operating system with Ethernet, USB, Bluetooth and 802.11a/b/g/n WiFi, and unless Microsoft has yet another secret tablet in the works the documents are likely referring to their Surface computer.
Microsoft is set to release the windows RT to the market on the 26th October, with the Windows 8 version to follow it is believed in January.
As of yet no pricing has been released.
