I've tried applying from Poland without any error messages appearing at least.

It's rather confusing though; why have a country drop-down if it's only open to US residents?

My guess is that they'll use it to gather demographics of people interested in the device. There was a ton of information to fill in that I'm sure any marketer would love to have.

Probably so that people think it's OK to apply from other country and do so rather than use some friend's or temporary address in the US to get the notebook.

Here's hoping Alabama doesn't have any towns with same name as my little UK town!
