Pros: Good solid e-ink screen, free 3g, solid ebook reader, good battery life, good ebook selection and pricing
Cons: No epub suport, no wifi, no memory expantion, battery not removabale.
Summary: Although a solid ebook reader (perhaps not as advanced as some of the newer readers out there but still very good) the reason I'm giving it such a low rating is because of the no support for epub file format. So what does Epub support mean? Well in the near future (a few years down the road) ebooks will be obsolete (like mp3, wma or aac are today), meaning that a universal ebook file format is needed so regardless where you purchased the ebooks they are yours and can be taken to any device and read on that device (also as an owner of an ebook reader you won't be limited where you buy the books, for example if you own a nook you can download an ebook from anywhere that gives you a more competitive price). With the kindle you bought a book, and paid good money for it, but can only use it on the Amazon device (they have their own file format that is not supported by any other device nor will it be in the future).
You pay good money for those books and yet you are entrapped (if you want to keep your books stay with Amazon, in addition epub is a more advanced file format than amazons kindle).
My reasoning is if you get a different ebook reader that supports the new universal file epub, you can always go back to any other device later on, but not the other way around. Amazon is still refusing to break the monopoly they have over their books, and even once they do decide to do so it will take them a very long time to change all their library.
