Android on a 46inch screen - GREAT.
Surfing the web form the sofa - GREAT.
Playing games as a family - GREAT.
Watching TV, Movies, Music Videos, with XMBC - GREAT.
Yeah, the remote isn't the best so you need something else, e.g. air, wireless or Bluetooth keyboard/mouse. I went with the RC11, might try a keyboard with integral mouse pad, e.g. the RC12 or K400 as I'm just not steady enough for it...but, it does the job.
Yeah, XMBC hangs on occasions when exiting - NO great pain, it's usually the time to turn off anyway. If not, power off and back on again and you're back at the Android screen in no time...
All in all, a MUST have.
