Apple may take more iOS features to Mac soon
An as yet unverified rumor asserts that Apple's "Back to the Mac" philosophy will continue with two more key additions. A 9to5 tip had both AirPlay Mirroring and iMessage in development. Although code references have alluded to iMessage coming to iChat, Apple was supposedly working on both a stand-alone app and an integrated client to determine which was better, possibly the same strategy used for FaceTime.
AirPlay has become an OS-wide feature on iOS but has had only limited presence on the Mac, where it's mostly limited to iTunes music. AirPlay Mirroring would cover most instances and could be a boon to workplaces or home theaters, where an Apple TV could be an easier alternative for presentations or movies than a video out cable.
iMessage for the Mac would provide a way of continuing a conversation once at home or at work as well as an advantage over BlackBerry Messenger. RIM's service is currently limited only to its phones and to PlayBooks tethered to nearby BlackBerrys.
