Now what negative about the free apps from Amazon.
All other free app's not work without registration, even if they are already installed on the Nexus 7. In Start an app always comes to point out that I have to register must at Amazon. I had the special offer of Amazon used for the free App's for Christmas. Now I have it all cleared. Especially came every few minutes at most, the reference to buy a Level or expand anything.
The advertising "free app's" is probably completely out of place for me a dumbing down of the customers! The apps run only in response to Amazon. Something I do not need. For that I would forgive zero stars!
