dunno about the one % bit..
My book died 1 week after I got it and a replacement took 5 weeks....I preordered and waited so I finally got a real working one after 2 1/2 months of waiting for it...........
Bookeen support sucked at that point & I did a straw poll of the number of people that had problems....here

That being said the only think superior to Cybook is a tablet PC...and their batteries suck.....
Compared to the sony ...irex..the cybook tops...now the only thing that make me buy something else is a 8-9 inch touchscreen e-ink...reader that you write notes on....hand written...
I would go for the cybook...but the Bebook seems to be good competition as well
