I have to say that the phone + TV combo looks like it should be the next 'big thing'
Just about every example here is a good one. The OnLive/Emulator/Actual Games & Apps example is certainly going to be a good option for the casual gamer. If you swap the controller for a BT keyboard, you'd have a nice couch computer. The Netflix/hulu/video example is also super convenient, especially if you're at a friends house who doesn't have video streaming services setup.
I know the micro HDMI out is picking up steam but I'm not sure it's 'standard' yet
