Hi, after looking around I've decided to get one of these tablets but not sure which one to get. Would very much appreciate user views. What are the differences between them apart from the HDMI port? Is there a way to connect the cobalt to the TV? Buying a tablet primarily to watch catch up and stream films. So I would want to do this. If there's not much between them and there is a way to connect cobalt to TV I'd probably go for that as it's cheaper in the uk at the moment.
