http://aldus2006.typepad.fr/mon_weblog/ (french site) says it's 129€, but there seems to be some confusion, because Virgin will offer 30€ of "gift card" to the 1000 first pre-orders...
What disappoints me is that
http://www.actualitte.com (french site again) had a live blog about the announcement of the partnership between Cybook and VirginMegastore, and they wrote this at some point
"Vitesse de défilement sans concurrence " pas convaincant lors de la démo
which could be translated by :
"Scrolling speed unmatched by concurrents" demo not really convincing
Well, we'll see when it's out !
