As I stood on my Surface RT long before opting for a suitable case or a suitable bag, here the short reference to the compatibility of the surface incl. Type- (and indeed touch) Cover.

The build quality is impeccable, but land lint quickly and easily visible on the black fabric of the bag and stick easily on Velcro firmly. The appearance is a matter of taste, but for me okay. And certainly a key factor: A good interior padding, the bag offers reliable protection.
