After receiving my Paperwhite, I considered its size ideal for a cargo pocket. To my surprise it fitted - even within my Dussel cover - in my jacket's inner pocket. The Dussell is a tight fit on the machine, and I have confidence in it. I feel sure it will do what it claims to do. You could put in a shopping bag and not feel nervous.I am getting more used to taking it out with me, finding it very handy for those desultory hold-ups - at bus-stops for example. It is surprising how much one can read in ten minutes! The touch key-board is very good, though I don't believe one can produce extensive notes and, unless I am mistaken, one cannot access formatting for italics, bold, underlining, etc. It is nonetheless ingenious, and the boffins will no doubt extend its facilities in the future. It is wonderfully light in the hand. The Cloud takes some getting used to, but it never fails to entrance me as a simple page-turn reveals more and more books of all sorts. Strongly recommended.
