Hey all, There's no particular orientation to the Magsafe power adapter, is there? The long cord plug has a ground and can obviously only be plugged in one way. But the little mini plug does not, and the 2 plugs are the same shape so it can be plugged in either orientation. I was wondering because I have a black plug without a ground from some other device that fits in the brick. I'm pretty sure there's no problem in doing that but just wanted to check. It would be handy since I usually leave the long cord plug at work. Thanks!
