Absolutely nothing. The only time I'll be replacing/upgrading any of mine will be if they break.I get that, although I can’t help but feel an upgraded one at the moment wouldn’t be enough of an upgrade to warrant most to make that leap at the moment - what realistically do they do with it to warrant an upgrade from the average user?
I completely agree, in my own situation, there aren't any located in a place where a screen would be desirable or useful.Screen looks ugly and out of place, just use your phone/ipad.
