Magsafe is the thing I hate the most in a MacBook. Maybe this is a third world problem, but this connecter is a dust magnet, and it routinely attracts so much dirt that I have to clean it up before the circuit is established. I so much prefer the PC connectors.
When I was about six, I had a powerful alnico magnet to play with, and I remember being quite intrigued that dirt would stick to it. Not all dirt, but some dirt. At one point I had a small jar full of magnetic dirt, collected by sweeping the magnet thru dirt and scraping off whatever sticked. As I recall, the magnetic dirt was darker in hue than the grayish non-magnetic dirt.
