We have found the G3 to be very impressive on all points.
We don't find it noisy at all as others seem to have done, it connected to our router within seconds.
So basically it is a PnP,,,,,,, BUT!, it would not start to begin with so my wife did a search on her iPhone and found other people have had the same problem, so after the 3rd attempt to boot up it I stopped preparing the box to send it back as it started up!.
It would be nice if there were a booklet or something to advise people of this, and that's the only reason I gave it 4 stars.
So we have no other issues apart from the fact our son has now migrated from his Xbox in his bedroom to downstairs to play games on it, .But the upside is we now see him more often,:).
