Number 2: no country specific sites. Well given that
http://www.amazon.com.au/ doesn't even exist that's not a suprise. Amazon is a company that hasn't fully capitalised on their namebrand. People know about Amazon around the world and would love to buy from them, but they are heavily US based and it is painful for overseas buyers. So that means exchange rates come into play more frequently, as do long shipping rates for overseas buyers. Apple and Ebay both cashed in on foreign markets, Amazon should too (in a better way). Who knows why they haven't, it doesn't make sense imo.
Extra reason: they have intelligence on the Apple tablet (lol), so want to get overseas consumers invested in Kindles before they lose the ENTIRE global market to Apple. That means rushing it out the door with all of the shoddy things attached to it.
