A few days ago Amazon released an updated version of their Kindle app for Android. They added a number of really neat annotation and collaboration features, but there was one in particular that they left out. It's not that subtle, so I'm surprised that so few noticed.
They didn't add the audio and video support that the iOS app has.
It might not seem like a big deal, but this is actually a major split in abilities. By limiting the media support to just iOS, Amazon are saying that it's not a major feature and they're not planning to support it. Media support will only be a gimmick.
If this is true, then it will give ebook media apps a shot in the arm. (Heck, they were mostly on iOS anyway.) That would be unfortunate; I liked the idea of having cross platform enhanced ebooks.
I'm going to wait and see if this support is included in the next version of K4PC. If it's not, then I'm right.
