I purchased and received yesterday the fingerprint ID type cover for my vaporous Surface Pro 4 i7, but after more closely watching Panay's presentation from the 6th, he seemed to imply that this type cover was designed more for the Pro 3 device. If the camera on the Pro 4 is adequate for Windows Hello, then would the fingerprint ID ever need to be used? Wondering if I need to exchange it for the regular Pro 4 type cover.
