Humm... My thoughts:
1. 24 hours? Flipping pages? My Cybook barely lasts that.
2. I use the metric system, so I had no clear idea about what 10,2" really are. Judging by the photos, it's not A4 sized. I confess I was expecting it to be a little bit bigger, but right now would be enough for my needs (PDF documents and manga).
3. 500 - 800€? That's too expensive. Specially if we consider that they will have to compete with Astak's and PL's. The iLiad v2 never had an equal in size, which in this case matters. Now it's not like that.
4. OMG!! I bought the Cybook just a few months ago!! What will I do?? Well, I guess I can wait for Astak and PL and decide then.

5. Anyone interested in a barely used Cybook?
