I got a 128GB silver Air yesterday. First impressions were that it is very slim and light. But in comparing it to my old Air, while it is slimmer and lighter, the difference is not that significant to me. I also have found Safari tabs are not refreshing as much, which is nice. But I have noticed that the screen seems less responsive than my old Air - though that could just be an issue with my unit. For example in playing a game (Simpsons Tapped Out) I had to sometimes repeatedly tap (four or five times) to get it to respond. Other times it did fine the first time. I did take a video of it doing it so I can show the Genius Bar. I also had a Newsstand button have to be tapped repeatedly, as well as a Safari page. I am also having a problem getting a couple of my Newsstand magazines to let me get access. This is not an Air issue - I guess their app or maybe iOs but it does make me wonder if I should just keep my perfectly good Air where everything is functioning perfectly...if it isn't worth the hassle to get this one going. All in all (if the tapping issue is remedied) it is a wonderful device. I am just not sure it is worth the $450 to me (after the price I have coming on the sale of my Air). Has anyone else upgraded from the Air to the Air 2 and if so, did you think the upgrade was worth it? I do think if you have anything other than an Air the Air 2 is a wonderful device and well worth the upgrade. I am just not sure I am getting enough of an upgrade over my Air to make it worth it.
