Great! I got the email notification of shipping this morning, and this evening the package was waiting for me at a neighbour's appartment. Of course, I'm in Paris, so it just had to cross the town to get to me.
Opening the package, I was impressed by the thinness of the Cybook Gen3. And it's no heavier than a paperback. But it feels sturdy enough to be used as an everyday reader, not just as a hi-tech toy. Though I wouldn't put it in a travel bag without its leather case, too.
I had no problem charging the battery, using the charger included in the Deluxe pack. Charging time is about 3 hours, that way.
Booting the reader, I was very to navigate and read. A few e-books were already available in the reader's internal memory, which was a nice surprise. I don't think I saw a mention of that on Bookeen's website, anyway! Included are two recent SF e-books: Charles Stross's novel "Accelerando", Cory Doctorow's novella "I, Robot"; plus a few public domain e-books in French and English, and previews from a dozen of Mobipocket e-books, from "Da Vinci Code" to Clinton's autobiography to "Internet for Dummies".
The one sheet quick start notice (in French and English) is very clear and useful, but I couldn't find the complete user's manual in e-book format that it said would be in the reader's memory. It's a little annoying, but at least, that didn't keep me from using the reader, because once you have it in hand, navigation is quite intuitive. The buttons on the side are neatly incised with icons depicting their use (switch to the music library, go, back to the general menu, etc.), too.
I had no problem exchanging files with my computer, too. The Cybook and the SD card in it were quickly recognized as external volumes by Ubuntu.
All in all, I'm glad I bought it. The ability to hold a whole library in a device the size of a single book is just what I needed.
Just one thing, though: if you have small hands, be careful to hold the device in both hands to read! In some photos I've seen on the Net, it was a man with big hands holding the Cybook.
