Query: A worthy replacement

If you're willing to trade a little style for some substance and save some money in the bargain, this is a very recommendable device. My Apple PowerBook power supply died in what is apparently typical fashion - sparking, crumbling wire where it meets the brick - and none of the Apple stores or CompUSAs in Atlanta had any in stock (which is curious in itself). I resorted to Amazon and decided to try this one out and I've been pretty happy with it. It seems sturdily constructed, and the breakaway cable is a surprisingly handy way to save on tangles. I do miss the plug-in charging light, but that's about it.
