Some interesting points above. I think alongside what people want from there phones is also an acceptance of the 'plus' phones. For people that just want to communicate and consume media there are plenty of larger phones at all price points from budget to £1,000that all do a decent job so IMHO a lot of people have consolidated their phone and tablets into the one device. This seems particularly true in android from experience of people I know.
Anyway, watched Safe on the Lenovo over the weekend and it was a great performer. Sound, screen quality and stand were all a great combo and battery life is superb for me. Didn't notice any drain.
Haven't really used it for much else and don't intend to so really happy with it.
