I´m off to NYC next week and plan to buy a MBA. Are there any precautions I should have in mind when buying it in the States when I live in Norway? Scandinavians have some letters on the keyboard (Æ, Ø, Å) that doesn't exist in the US, but I understood it's possible to change the settings on the MBA to Norwegian? Off course it wouldn't be visible on the keyboard, but when I type, it will substitute the US signs that are already in place? Have I understood that correct??? Any experience or advice on this? Also, will the warranty be valid in Norway if I buy a 3 year AppleCare Protection Plan? Grateful for any comments!
