Hi, guys I'm deciding on an apple remote... I want to control movies (played from a MBP) on my TV. But now I saw that there is an Apple iTunes Remote application for iPhone. I'm not sure if it would be able to replace the need for apple remote. How does iPhone communicate with the MBP? Bluetooth? Would this be a decent and free alternative to apple remote or you think it'll be better to spend the buck and get the real thing.
