I put a deposit on a new P4, so now I'm looking for a display. The iPad mini 2 with wifi/cellular 16gb is $199 brand new. Seems to be the right size and has all the features, although I wouldn't activate the cell service. They have 32gb models for $250 but I don't think extra memory is necessary since this will be used exclusively for the transmitter. Will that fit ok on the controller?
