My three hours of charging were up about an hour ago (hooray!), so I started playing around with the Cybook. My first impressions: wow! booting up is
fast! The display is lovely -- the contrast between light grey background and blackish font is just great, imo. There's a lot to discover, but it takes only a while until you know which button does what.
Button pressing: yup, the buttons for page turning are somewhat awkwardly placed; the Menu button in the middle would have been a better choice. And indeed, you have to exert some pressure to make the page turn. I guess I'll get used to that, though.
Library: navigation is not ideal, especially if you've got many files on your device. I've renamed all my e-books and inserted a description of the genre in the file name, so iif I sort the library according to file names, I've got at least all the mysteries, all the romances, all the classics, etc. in one place.
As a first-time user of an e-reader I was, of course, curious how difficult downloading a book from one of the online bookstores is -- not difficult at all.

I've already bought several books on Fictionwise and registering the PID, downloading the books, and transferring them onto the Cybook went smoothly and without any problems. Hooray!
So now I just have to find time to read all those new books!
