I now own a Kindle. It was my birthday present. When they first appeared I had no desire for one. The biggest limitation was that they only read Kindle books. Now that they can read txt, rtf, and pdf as well, I have a use. I own over a thousand rtf, txt, or pdf books (plus a bunch more in .lit format as well). I got tired of reading them on my laptop, however. Finally with this latest model I saw a use for one.
Several books have already been transferred from my computer and several others acquired free from the kindle store. I have greatly enjoyed reading on it.
