It does the job nicely, small and slim so easy to pop in any bag and doesn't add to much bulk to an already slim product. Although the felt material on the inside does flake a little bit sticking to the screen.
I would agree with a lot of the previous reviewers. I too was disappointed with the poor viewing of PDF's but after using Calibre Management to converting all my files and ebooks to epub format, everything uploads so easily. Battery life is good and I can easily read a few hours every day without having to charge for a couple of weeks. Page turn seems a bit slow, but you get to used to it. Would recommend getting a good cover for it as the screen is very much a dust magnet. Only one small gripe - the power slider to turn the device off requires you to hold it in place for too long berfore it finally kicks in.
