Hi,
I recently bought the Cybook Gen3 and wanted to share some of my thoughts, since reading on these forums really helped make my decision. Think of it as a way to say 'Thank you'
First off, I'm very happy with the device. I used to read on a Palm handheld a few years ago, and the Cybook combines the flexibility of ebooks with the readability of dead trees.
I mainly bought the device for reading scientific and/or technical PDF documents and was pretty ancious to see the PDF support on the Cybook. While it's true that reading in portrait orientation is pretty uncomfortable, but still (barely) possible, I found that reading in landscape mode and flipping the page is very comfortable, not only in text size, but in holding the device as well (try it!). For other reading, I use the Mobipocket Creator offered on their website to convert the documents, though I've only tried a few Project Gutenberg-texts so far.
Connecting the Cybook to a PC works great, and I've had no problems so far with the 2 GB Kingston-Card I'm using. Also, first order of business after unpacking was slapping Times New Roman on the device, and it just worked the way it should. It's a kind of no-questions-asked, down-to-the-minimal device I really like.
I got the leather cover for the device, and, although it obviously isn't leather, I think it's a nice addition. I use it for protecting the Cybook while I'm on the road, and for that, it's great. Snug fit and the device is still usable.
As for my wishlist, there's nothing really high priority. Organizing the library in folders would be nice, but I can do without. There should be more PDF zoom options, if only to take a closer look at the occasional figure or the sub-/superscript in mathematical formulas. And at last, from the would-be-nice-but-I-can-do-without is support for 'ZIP books': some image files (numbered or whatever) in a ZIP file, to be read like a book. Imagine reading some graphic novels on the Cybook...
Sorry about the long post, but maybe it will help people deciding. At least the way I see it, the more mainstream ebooks and readers become, the better for all users.
Greetings,
Manichean
