Signoflazurus, the guy there actually told me the Kindle is just for ebooks, but can be used as a tablet. I have to say though the fact that it isn't regarded as a tablet and will thus not be used by most as one, I think it's made it more alluring to me. But at the moment it's just out of my price range.
There are different kinds of kindles and 2 main categories, one being the ereader kindles that you are referring to and then the more expensive kindle fires which run a modified version of Android that Amazon cooked up so that it integrates with their systems better.
