If microsoft start charging monthly then I would have to move linux or something. No way am going to subscribe to an operation system. Total hogwash!
Windows phones updates should be for free as well, No big OS updates please, do it like android and keep updating bit by bit.
Also don't pull a idiotic move again like you did with the wp7.5 devices by blocking windows phone 8 updates.
Maybe the OS backwards compatible and apps backwards compatible.
