Sending SMS from your computer to any iPhone / iPad is a nice feature... though I wouldn't piss on the dictator, as it is slow if your typing skills are adequate. It doesn't dictate as you go, it records everything you say, you finish, then it starts dictating via an online translate function back at Apple. So you need a connection on the device for that feature. Typing is faster though IMO.
Overall though... a really nice streamline of Lion itself.
