I've been having a few problems with my Cybook - the support team gave me a replacement but it was still faulty
It's just too frustrating to even look at! So, I'm on the lookout for a new reader.
The Cool-er has a lot of potential but I personally wouldn't buy the first generation. Plus, if you're in the UK, might as well get the sony prs-505 from John Lewis (if you want red/silver) or from waterstones for £199. The offer ends 1st June for JL.
I think for just £10 extra, I'll go for the Sony (*red*) even though I really REALLY love the Cool-er's colors! *so pretty*
