Bought one for myself, lent it to my girlfriend when she went travelling and she loved it so much I let her keep it. Also bought one for my 87yo grandmother whose sight is failing, and can only read large print books, which are rare, big, heavy and difficult to read. Up the font size on the Kindle and she's loving it. Of course I also have my own too.
Highly recommend reading David Dalglish, he has really cheap books on the Kindle that are among the best I've ever read. They're also based in a world quite similar to CF and were the inspiration for my return character.
