The only thing I dislike about my Kindle is that I cannot create folders to store my books in a manner that makes sense to me. Other then that, I love my Kindle. It is easy to use and light weight, unlike many of the tomes I enjoy reading.
Why?
My reading has greatly increased since I was given the Kindle because it is so much easier to buy books. I don't have to go to the store and hope to find something I like, special order a book that I want, or wait in line at the library for the book that I want.
The books that I have bought have been under $10 a pop. There are only two books that I have purchased over that price point and both of those were new releases. Had I waited a week, they both would have fallen to $9.99. Even when I paid $15, it was still $10 less then what I would have paid for the hard back.
I love that I have all of my books with me where ever I go. Right now I have 47 books. I know that there are people here with thousands.
Why Kindle and not Sony?
I like that when I buy a book through Amazon, Amazon stores it for me. If I delete that book, I can re-load it for free. Essentially, Amazon acts like a library for all of my Amazon books. I do not know if Sony has this option.
I like the Whispernet. I really don't use it that frequently, I order most of books online while at work so I use the Whispernet mainly for downloading the books onto my Kindle. I like the idea that I can be sitting in an airport in most of the US and I can browse and download a book very quickly. I could not do that with a Sony.
