Amazon is going all out with its line of Kindle Fire HD tablets, now taking pre-orders for the devices in more than 170 countries. To go along with this, the company is rolling out its Android Appstore in 200 regions. That's a giant increase in availability which could potentially put Amazon's tablets in the hands of many additional users. Before this move, the Kindle Fire was only available in a total of seven countries – US, UK, Germany, France, Italy, Spain, and Japan.

Amazon is going head to head with Apple in terms of availability for its tablet. In fact, the iPad is sold in over 50 countries, so the Kindle Fire is now offered in plenty of regions where the iPad is not an option. Will it be able to outsell Apple's slate? That remains to be seen, but this global rollout certainly gives it far more reach in terms of potential buyers.

Specifically, Amazon is bringing its Kindle Fire HD and Kindle Fire HD 8.9” to the new markets. It plans to ship the devices on June 13 to customers in Ireland and Gibraltar who order from Amazon's UK store. The same date applies to those in Austria and Luxembourg who buy from the German store, and buyers in Monaco who get it from Amazon France.

Amazon sells its tablets at low margins to keep the price reasonable, and it hopes to generate income through its closed app ecosystem. The Appstore is available now in the new regions, so as soon as the Fires are shipped, customers will be able to start buying applications, games, books, and other forms of entertainment.
