Just a couple of things.
They aren't allowing reviews on the phone at their sales page for the phone. Apparently they don't allow reviews for unreleased items, and yet a number of pre-ordered items sitting on my account this very moment which will not release for months, have plenty of "reviews" and I can't say that I can recall this ever being the case before now.
The list of "Favorites in the Amazon Appstore" is pretty damning. Those apps are just the bare essentials that your platform has to support, and a sprinkling of what I'm fairly certain are made up or knock-off apps. I couldn't find the Lili, or To-Fu Fury apps anywhere in their own store, and Snow Spin looks like a Chinese ripoff of a better game. It's pretty comical that the selection there is so sparse that a game with a total of 2 5 star reviews, manages to make the cut for "Favorite" status. Imgur copy in case they rethink this.
