This can be misleading. I bought my Macbook Air in Portugal, had 2y warranty there. Then moved to the UK and the brick stopped working. Went to an Apple Store and since it was after the 1y warranty offered when you buy it in the UK, they rejected replacing it for me. Eventually went to Portugal to visit my family and got a new brick from the same store in 5 minutes. On a curious note, there's no Apple Stores in Portugal yet so in this particular case it was even more interesting to realise how much better help I got from a non-official store.
