I love my Cybook, and have had only a couple of problems with it. Here's my take on this whole issue:
I had the money to spend on an expensive "toy". I don't usually (well, in fact, almost never) but I considered it a combined Xmas and bday present to myself. I've been interested in ebooks for a long time (before I was a teacher I was an academic librarian.) Years ago I wanted a Rocketbook, but couldn't justify spending the money, which all went to raising my kids. So for a long time I used a Palm. I'm happy to be part of the world that takes a risk and tries out a product that the masses may not want or be ready for yet. If I hadn't had the money to spare, or if I hadn't been truly interested, I might be more bothered by a few of the eink reader issues. But overall, I think the Cybook is a great product. I'm keeping my fingers crossed that I don't get an irreversible crash, but even if I do, I figure I'm just part of the whole push toward better (and cheaper!) ebooks.
Just my 2 cents. YMMV.
