Hi, a simple question. I'm going to the US in a few days and plan on purchasing a macbook while I'm there, since they're about a third of the price without the taxes and all. Was wondering what to do with the transformer when I get back. As you know Europe got 230V and US got 110V. Plugging a 110 computer in a 230 system would blow it up (I've done it before) but usually they have some kind of export switch somewhere so you can make it work with either system. Or even more clever use the power cable as a transformer just changing the plug. Does the macbooks have that sort of thing? Or could I just change to a european power adapter and it'll work anyway (if the transformer is in the cable that is). Thanks, /Fred.
