Sorry Harry, I asked the origional question because I have a Cybook and it went diagonal sqaures on me and my computer wont recognise it and in the end after trying everything Bookeen said it is on it's way to France (Bookeen). So, I have had my Cybook one month over a year and the case is lovely but seems to have become loose around the Cybook and I have had to catch the Cybook as it has slid out of the cover more than once. So, yes it does happen.
I have cancelled my order for another Cybook. Bad feeling about the backordering. First they said July 1st, then August 1st and now maybe August 10th the next Cybook order will be in. Maybe. I Have ordered a Bebook. Will be here by Friday. Hopefully. Have learned never to count on shipping. So that is my decision. Of course will keep my open for a backup of something.
