the fingerprint scanner on the back is actually incredibly useful, at best it is placed just where you would put your finger whilst holding the phone in normal use, at worst you tap your finger and move it to the more comfortable position. I agree that any other buttons on the back are not useful but having had this feature on my phone for a few weeks now I would hate to go back to always needing to pin unlock it.
