Amazon is luring developers to their platform with a clever Amazon.com tie-in. Developers who choose to integrate Amazon purchasing into their apps via a linked Amazon account will earn up to 6% of purchases. The deal seems like a win-win as Amazon supports their dotcom and app ecosystem while developers gain another revenue stream. With that said, the Kindle series holds a slim 4% market share in the tablet space and will need to have a lot of developers buy-in if they want to have success over the next year or so.
