@Alistair:
You are right. Apple pricing in the EU and Switzerland is an issue in itself.

Considering that all Apple computers are perfectly multilingual, all installed software and the packaging is international, it just boils down to different keyboard layouts and a different plug for the mains socket. Asking a 20..30% premium for EU/CH is just ridiculous and I have expressed this view more than once to Apple.
I got lucky with my MBAir11. A Swiss retailer recently celebrated his company anniversary and offered a general 20% discount including Apple products. If it had not been for this chance I would have asked one of my US colleagues to bring me a MBAir on his next trip to Europe.
