I'm three weeks into use of my new MacBook Air and it is a beautiful, well designed machine which makes its few shortcomings all the more irritating. Fast an pretty in all ways that count. First flaw, the MagSafe2 power connector sucks. This is the third Mac Book with a MagSafe connector I've had and the first two were great. On this MBA if the cat brushes his tail against the power cord it decouples and I have to go chasing the connector under the desk. The "Mag" part of the plug is too weak and the constant falling out drives me to distraction. Secondly the trackpad/selection button combination is not intuitive and I still haven't got the hang of it. I'm forever clicking too high on the trackpad and of course nothing happens. I understand the desire to have a bigger trackpad, but something to give the area of the device that takes the "mouse up"command a different feel would be nice. I'm going to try a piece of tape but it may make that part of the pad unresponsive.
