Other tablets have no true purpose or useful content to consume. There is no thought put into the user experience of the Galaxy Tab or the like. They are simply "me too" devices and fall into the meme of "ipad killer". Where, as w33ble put it, the Fire is an Amazon Portal.

Apple and Amazon are in the same space but came from two different sides. And Apple is trying to cover the "harder" side, which is server and cloud computing. While Amazon had that down before diving into consumer HW.

I do think they are missing an opportunity without a camera. Think about the opportunity to scan bar codes or book covers and instantly see the Amazon price, and purchase right there. Imagine being in Barnes and Nobles and buying the book on your Fire.
