I have an American MacBook on the way, and live in the UK. I'm wondering if I just need a simple adaptor to use the power supply in the UK? What concerns me is that the travel adapters that Apple supply provide power for: It is slightly concerning that the power supplies don't list the MacBook, but on the other hand, it could just be the Apple site updatey-people are too busy hurling new stuff around to bother editing old descriptions of adaptors? It seems to cover only older models, and I don't see why they'd design the MB to be a power-bitch, so I'm not too concerned, but it would be nice to have clarification. Thanks!
