We saw the launch of the Kindle Fire and have seen Amazon's hand with the custom build of Android that looks/feels nothing like Android... anyone have any guesses why they would want WebOS? Amazon already has the Android store, all the Android integration done for the Fire and the Java/Android expertise in house... where does WebOS fit in?
Does it have to be the webOS division? I'd imagine Amazon wouldn't have that much interest in Palm's software, but Palm is also one of the few entities in North America that has experience designing hardware from end to end. We know that Amazon had to outsource the design and build of the Fire to an outsider, no doubt it would be preferable to bring that in-house to a team of world class industrial designers.
Maybe Amazon just want some patents, some good engineers and a backup OS for leverage against Google?
