The Amazon Kindle Fire is a tablet version of Amazon's e-book reader known simply as the Kindle. The Kindle Fire has a heavily modified user interface that doesn't appear to be running an Android OS in many ways. Users have access to an Amazon App store, which includes many apps from the Google Play Store as well as access to Amazon's e-book store. The Kindle Fire has 8 GB of internal storage with 6.5 GB accessible by the user. Cloud storage is used for all digital content purchased through Amazon.
