Query: This isn't right.

It isn't right that amazon controls the content of your Kindle. That they can delete items when they see fit. Amazon has stated that their aim is to make the device disapear and the content stand out. That using a kindle should be just like using a real book. That can't be the case while Amazon only allows you to rent books, and fails to give customers what they promised.
