If it is the US website I'm just asking where the international english website is I guess. Choosing UK or South Africa doesn't make the inch go away.
This is totally fine for companies targeting US domestic markets I guess but I suspect Apple sees itself as an international company and they should have the budget for proper internationalization.
Maybe they just don't care for people to know how thin the Air is, but the number of search results for 'thin' on the page let's me think otherwise.
