Just got my MBA 2.0 128/ssd. Everything else is flawless (4-finger swipe included) however the only problem is the screen lines. My question to everyone is how many think it is hardware and how many think it is software that can be fixed through an update. I don't know if I should press my luck and keep it or try to get it exchanged.
My first MBA 2nd Generation had the lines and the 4 finger problem. The 4 finger problem I do not care about since it seems to be software related and easily can be fixed. Although it's not quite as satisfying to deliver products with advertised but lacking features. Anyway.. The display problem matters. I had send the MBA back.
I got my second MBA yesterday while booting I almost thought I got one with no horizontal lines but then when the background changed from gray to different colors ... I could see them again. They were noticable fainter than on the first MBA I got but they were there. I thought quite a while what to do since I had already sold my first Generation MBA (which did not have such line problems) but then I called Apple for sending it back getting my money back. The device is just to expensive for coping with such a display.
Nevertheless I had "exminded" the display quite a while since the lines were fainter than on the first one and the nearer I got the less you could notice the horizontal lines. From normal working distance they were visible. Approaching the display to about 6 inches they barely visible further approaching to about 5 inches or nearer they were not visible at all.
I definitely doubt that this is a software problem at all. From my opinion and with the different distance behaviour of the screen this probably must have something to do with the surface coating thus being an hardware problem.
I am quite disappointed. In retrospective selling my first Gen MBA before getting the second Gen was not such a good idea. But I hadn't expect this device to have such problems. After the heat problems of the first Gen MBA and the improved graphics of the 2nd Gen MBA I finally hoped to now have an almost perfect light device I really could use. The more disappointed I am now. I want a MBA but they can't deliver a satisfying one ...
By the way, both devices were build in week 45.
