To anyone complaining about country restrictions:

Selling books is actually quite the complicated matter in some countries. At least in Germany you are not allowed to sell a book at a price of your choice (http://en.wikipedia.org/wiki/Fixed_book_price_agreement)

It can be pretty fucking annoying to have these laws in place (they do have their merits, but... that's a completely different debate), but I can understand Amazon not having worked out all the legal issues to go worldwide with this
