I got to say, I prefer ebooks. They take no space, they do not decay, I don't have to box them up and move them around every move. I can navigate, search and take notes in them much more efficiently. If it's a book I want to keep the information, I will pay a reasonable amount for an ebook (under $10).
I have gone as far as scanning entire books for the benefits above, although this is far from optimal...
I thought this would be a book I could read in a week and absorb everything I needed... But it's a book I want to keep. So I'll probably pay the $9.99 for a digital version.
EDIT: I was only able to make the transition after ereaders took ebooks off the computer LCD.
