The family bought me one for my 70th birthday. Ilove it. As an avid reader, books have always been a weight problem when travelling light. Kindle solves that. I have a wide range of down loaded, mostly, free books, including Complete Shakespeare. I have all of George Borrow: just finished re-reading Wild Wales. Users of this site make like to know that a whole host of US Gov survival/bushcraft books are downloadable free and a range of similar titles are very cheap. You can download a sample free before deciding whether of not to buy. I keep mine in a waterproof zip pouch but it also fits easily into a small ziploc: this has the advantage of being able to read it while still protected from the elements. As for knocks, I've dopped it without harm, but I don't expect to throw it about. Battery life seems Ok: so far I've read four full length books on it on one charge.
