How long will it takes them to drag it from the CD onto their desktop? 
Very few people will have the time or inclination to photocopy a book 
(outside of university students that is) so the loan of a book very 
rarely results in the creation of a fresh copy. But a PDF? It will take 
no effort at all to copy and people will probably do it just to get your 
CD out of their drive and get it back to you before you start to nag 
them for it.
