I read my first book on the Kindle over Spring Break. I love it. I almost think the print is clearer than on some books (especially those paperbacks with the cheap paper). I'm not so sure about reading blogs on it...the one I choose was Librarian in Black. It has a lot of links to other sites. The Kindle is NOT a good internet browsing device. I found it very difficult to explore those links listed in the blog. I will most likely unsubscribe from the blog.
I discovered it is good to watch the Amazon Kindle blog...they often have offers for free books (usually limited time offers).
