Please bear in mind that most of the problems that "early adopters" had have been fixed by subsequent firmware updates. Eg, the original firmware would crash on lookup of certain words in certain dictionaries (or simply not find them, even though they were present). That bug hit a LOT of people, but was fixed in firmware v538.
To say, therefore, that "there's almost a 50/50 chance that the Cybook you will order will have some kind of problem" is erroneous, because the current models do not have these bugs.
One might also ask "what is a problem"? Is the fact that the occasional button press is missed and you have to press the button again to get it to register a "problem"? All CyBooks do this, and yet the votes in this poll clearly demonstrate that for some people this is a problem and for others, it's not.
I'd take the results of this poll with a
very large pinch of salt
