Two models of Surface will be available: one running an ARM processor featuring Windows RT, and one with a third-generation Intel Core processor featuring Windows 8 Pro. From the fast and fluid interface, the ease of connecting to people, information and apps that users care about most, Surface will be a premium way to experience all that Windows has to offer. Surface for Windows RT will release with the general availability of Windows 8, and the Windows 8 Pro model will be available about 90 days later. Both will be sold in the Microsoft Store locations in the U.S. and available through select online Microsoft Stores.
