Amazon today took a big step forward in its strategy to take its app distribution business — and its Kindle Fire hardware business — global: it announced that its Android-based Appstore will expand to cover “nearly 200” countries, including adding Australia, Latin American countries like Brazil and Mexico, Canada, South Africa and South Korea. Up to now, the only countries where the Appstore was available were the U.S., UK, Germany, France, Italy, Spain and Japan.
