Query: Long time ebook users

If been using ebooks since the original Rocket Ebook was released. The Kindle is a great ebook reader. All the features of the Sony ebook reader, with the additional of being able to access the Kindle book store wirelessly. Also comes with a built in dictionary that is handy (Sony does not have this either, although the Rocket ebook did have this feature). It's smaller than any of the Rocket ebooks, but a bit larger and thicker than the Sony ebook. I like the buttons for the previous and next pages, although they are easy to hit at times. Sony's prev/next page buttons are a little uncomfortable to hit. I find that the prices of the books are cheaper than the same books on Sony's Connect store. Overall I am very happy with the Kindle.
