Today Amazon launched the Amazon Appstore for Android (more here and here). At this point, there are a slew of app stores (from your phone, computer, tablet, browser, television, alarm clock, etc.

But this is Amazon… so it’s worth paying attention because:
1. their scale and brand makes them a major player
2. they will do it in the Amazon way… technology, recommendations, price competition, etc

Did I mention price competition? Amazon launched behind Angry Birds Rio – giving the uber-popular game away… for free. It’s the #1 selling and grossing application on the iPhone. On Amazon, it’s free for today’s launch. That’s quite a promotion.

And it represents a larger pricing move: Amazon Appstore will give “a great premium app for free every day.”
