Not to get off topic of this thread, but
@ardeegee: eReaders and ebooks have the potential to help academics or students in tremendous ways. The ability to store 100s or 1000s of PDF journal articles, or academic texts, and to take them with you, to note on them, to make separate notes, and then to use those notes for analysis later is a dream chore for those of us who need it. Imagine when you were in school, and you needed to read a book for a class, and you could download it, make notes on it, and then later use those notes to write your paper. Sadly, the software that Sony provides is very very badly adapted for such uses, especially for those of us on macs.
In any case, I never finish a book without scrawling notes all over it, with post-its and folded over pages...I can't imagine NOT writing all over a physical book, unless it was made of gold and I wanted to resell it.
