I don't know if I'd put the Kindle Fire on this list, it's really in a class of its own. Sure you can load Android apps on it, but it's mostly a way to consume media purchased through Amazon. As far as I know, you can't easily access the Google Play store, and as a dev, I know I'd have to reconfigure my app to make it available on the Fire. (I use in app purchasing)
Very best collection and useful information to find all kind of tablets on one platform
