Cool. Now if only Amazon would eat its own dogfood. Their Prime Music/Cloud library music player still requires Flash in order to use.
They do this because flash ads are now no longer seen by a large enough group of users which makes them bad advertising vehicles.
Maybe at some point the Prime Music people will decide that a large enough group of users are no longer able to use their service, but that is a totally different decision with different motivations.
the video reviews are flash still too.
