I might have gotten a little carried away, but I really want you to see how versatile this cover is. The animated gif's starting point is the picture that says, "Best Kindle Fire HD Cover!" and continues on to show you how to fold each stand and how each angle looks with the camera located in both directions.
One of the other Kindle Fire covers (with both stand options) that I considered buying was unable to do this as there was no hole for the plug. The developer said this was to protect the ports from dust, but really it just hampers the user from charging their tablet when the cover's closed.
In the world of you'll find both Kindle Fire covers and Kindle Fire cases, but it's not very clear if they're the same thing or if there's a difference between the two.
A cover, on the other hand, is always attached to your even while you're using it (unless you remove your tablet from the cover of course). Thus a Kindle Fire cover is "covering" your Kindle Fire both at rest and at play.
