I sort of feel the same thing about the book Cryptonomicon by Neal Stephenson. I am pretty sure I started reading this when I was living in Liverpool over 3 years ago. I finished it this afternoon. I has forgotten some of the characters, during my long period of not reading it. I think I stopped reading when one of my favorite characters got addicted to morphine (Iam romantic like that).
The book is very hacker friendly. It has not dated that badly, apart from a section where he stores some data onto a floppy disk. If I was more keen I would have played with the perl script included.
I did enjoy one section, where one of the mathematicians writes down an equation for the amount of sex he needs to work effectively.
