There is no such thing as the Microsoft Surface, there is the Microsoft Surface RT(ARM) and the Microsoft Surface Pro(x86). The Surface RT, like most ARM devices(Android & iOS included) has a locked bootloader. The Surface Pro on the other hand will have the option to "unlock" the bootloader by disabling secure boot. I do wish Microsoft would take the "high road" and offer the same option to disable secure boot on the Surface RT.
