All good things come to those who wait
I've had my Cybook just over a week now and have completed two large books. The current firmware seems pretty solid, and is largely ok for the task of reading (Thats all I use it for).
It seems that the two most wanted features would be page numbers, and directory support.
As far as i'm concerned page numbers aren't neccessary. The only time i've had to use them, or will ever use them is when my bookmarks disappear. When I had this problem it did seem to be directly related to a problem with the SDcard and seems ok now.
It is important to me to have an idea of where I am in a book, even if just to give me an idea of when I need to be looking for my next one. I would hate to be out somewhere and realise that I had nothing to read. In this case the pageometer works fine.
When I had the bookmark problem then the pagenumber may have been useful, but I doubt it, even reading a paper book, page numbers are not something I pay attention to. If I ever loose my place then I usually end up flicking through until I find where I was upto. It's just much slower on a cybook. For this reason the bookmarks need to be 100% reliable.
Maybe for those who insist they need a number at the bottom of the page, a percentage would suffice.
As for folders, I've only had my cybook a week so it's not an issue for me at the moment. It likely depends on how you use the cybook.
In my case I have a collection of books that I have read many times, and will read many times more. I would expect over the next couple of years to buy many of these for my Cybook and eventually this would cause me issues. Paging through 100 pages of books at cybook speed doesnt sound like much fun.
Cybook obviously intended for large libraries to be kept on these devices by including the 2GB expansion. This being the case then the library could be better, although not necessarily through the use of folders. A possible alternative could be to have a more three dimensional database where a person could browse by genre, author, year, etc
If Author was selected then the library page would show only Authors, and only when an Author was selected then would a list of books by the selected author be displayed. This would be a true library feature, unlike the present which merely displays all available media.
Even if a better library(or support for folders) wasn't ever to be included it wouldn't be the end of the world. I would keep maybe 10 books at a time on my Cybook and keep everything else on my PC. Would save me worrying about bookmaks being saved on my SD card, because I wouldnt need one. The lack of this feature however could ultimately take me away from Cybook to another company that makes or starts to make E.Ink reading devices that do include this feature.
