Query: Very Cool Device

I love the kindle. It looks and feels great. I found it simple to use and navigate. It is amazing to have a new book on it in seconds. I can take it anywhere and have a full library of books at my fingertips. The software update allowed me to put my books into categories which better suits my needs. Lots of reading hours will be enjoyed with the device.
