I have a surface 3 and want to purchase the type cover, but my local store in Vietnam doesn't have it. They only have surface pro 3 type cover model, which is known to be larger than the one I want to buy. I do not mind the dimension difference but can the type cover for surface pro 3 be used with my surface 3? (specifically the mount point) On a side note, I know this is kind of weird but I have no option to buy the right type cover model. And the store does not have display sample so I cannot try.
