Details from ActuaLitté (thanks to Nicholas Gary). Google translation here. Cybooks—at least some and maybe all—will come preloaded with French and English classics.
A bare package will go for 350€; a deluxe one, for 450€—with a 2G SD card, a USB charger, a headphone and other trimmings.

There’s also Orange and SFR (the two biggest mobile phone operator in France) who are beta-testing their ebook reader solution:
