Why is it called a Kindle anyway?

Yesterday, I went and ordered a kindle. While the initial expense is up there, I figure that I will be able to save in the long run, especially on out-of-copyright books. A class I must take for my English major that will use the Kindle particularly is a Shakespeare class. I am sure that in the class we will be reading plenty of them, and having a kindle will definitely help, as opposed to finding either physical book copies, or reading them on the web. It will also save my poor back from having to carry around all of my books, which may be even better than anything else.

Will be updating soon on my first impressions of the Kindle DX Graphite.
