thank you all for the quick replies!
Concerning my last question: Can I sort books in subdirectories (like Science Fiction, Biographies, Science, etc...); or are there pre-defined subdirectories to put the books in? or just place them on the root of the disk?
sorry for the many questions.. I'm on the virge of getting a 505 or 700,depending on if I find the extra $100 of the 700 justified enough...
So,I'm kind of excited already
