Amazon tends to be a bit focused on the United States because, well, it's a US company. But they're expanding the reach of both the Amazon Appstore (which now works in almost 200 countries) and the Kindle itself. A press release this morning announced that the Kindle Fire HD is now available for pre-order in more than 170 countries, in both the standard 7" model and the premium 8.9". Hardware will begin shipping out to customers on Thursday, June 13th.
To say that they're a bit late is an understatement - the 7" tablet has been available in the US since September of last year, with releases in France, Germany, Italy, Spain, the United Kingdom, and Japan before the end of 2012.
