Why didn't they just make iMessage the goto messaging app for everything iOS/OSX...just like they did re: video with FaceTime??? Those who still use iChat can carry-on doing so. As a non-iChat user would've been excellent getting all msgs that way...with an option to freeze related iOS or OSX device notifications if I happen to be using both at the same time and don't want to hear and see duplicate notifications. Sometimes Apple really surprise me as to their oversights. What they should really do? Offer even PC-users free @me.com email addresses and let them FaceTime and iMessage with all us iOS-users, via free software. What will that do? Encourage them MASSIVELY to buy an iOS device so that their messaging needs are met nice and tidily, at the desktop or when out and about.
