In the works:Maybe it's a stupid thing to say and maybe it points up the reason I'm a loser and not an inventor, but I personally believe even half a century from now you will be holding essentially the Air of today. Sure it may be marginally thinner with slightly smaller bezels but that is it. The human eye already can't discern a pixel on the screen, so no improvement to be had there. Battery life could probably be improved but already it is at the point where all u gotta do is charge it while you sleep and you can use it all ur waking hours and then some.
Ultimately, it's a screen. Nothing more or less. And I believe evolutionary technology, mainly pioneered by apple, has led to the point where things have been reduced to their most basic elements. The Air is about as basic in this regard as you can get. It's you and the screen. That is it. In terms of weight, thickness, display, performance......there really is not much of anywhere to go. Can you seriously point to one way the Air could be improved that real people and not techno geeks and video and audiophiles care about? Nobody cares about that fingerprint gibberish and 4k tv.
