Listen, the one huge thing they need to do about the MagSafe is to make it a cable, you know, like with a connector at each end, instead of making it allong dongle on a power supply or smlomething else. The wire that connects to the MagSafe by the mac lasts a couple of years and then it breaks. I know; I'm on my 3rd one. Unfortunately, you have to through away th whole damn thing, power supply and all, because you cannot (practically) rewire the cable. I've tried. It is absurd that a broken wire you can even see requires you to throw away $65 worth of hardware. It's not only absurd, it's stupid design.
