Perhaps I'm a bit of Luddite (I've been called worse) but can anyone actually give me a good reason why anyone would want to read a book on one of these, as opposed to just reading from a book.
I find there to be little difference reading on a Kindle and reading from paper. What I am finding with my Kindle is that I'm using the dictionary more and so improving my vocabularly; I'm downloading some great free novels and having some great interactions with the author, and when I've finished reading I can browse and buy exactly what I feel like reading next, not only what I have laid by in the house. So, I guess it isn't that reading on a Kindle is superior to reading a book but there are things associated with a Kindle that you don't get with books.
