iOS has never had an answer to RIM's BBM, but now it does. iMessage supports iPhone, iPad, iPod touch. (What, no Mac OS X Lion?) Users can send text, photos, and video, and iMessage supports group messages. There's delivery receipts, read receipts, and typing indications (so you know the other person is talking) represented by three little dots. Messages are pushed to all iOS devices at once if you have more than one iOS gadget. Too bad iMessage and FaceTime aren't integrated. At least not yet.
