A bit off-topic for this thread - but if you want to be cured of this concern, stop in at the London Apple store, as I did yesterday (in town for the traditional Presidents' Day FT Do), and compare prices. They probably bear the same relationship to other UK prices as US Apple store prices bear to other US prices, but they're still scary (to this Yank). The MacBook Air section, by the way, was mobbed. I didn't watch it long enough to see if anyone was buying, but there was sure a lot of interest.
