While Amazon's tablets may not be running stock Android, but rather a forked version of the OS. Their Kindle Fire tablets are still quite popular. The Amazon Kindle Fire HD is a great tablet for reading, as well as playing some games, along with Amazon's App Store and their free app of the day. Right now Amazon is selling their 7-inch model for just $99. Now this does include "special offers" aka ads. So be aware of that.
