For me PDFs have several advantages. I went through hurricane Wilma and some of my older gaming stuff got waterlogged most of it was out of print so I replaced a lot of it with PDFs.
They cost less and take up less room and they don't weigh as much when you have to move.
A lot of the people I play with don't have money for a lot of books so if they want to say play a warlock instead of loaning out my book ( I hate loaning out books) I can just pull up the PDF and print out the pages for the warlock.
It is nice when prepping for a game to just print out what you need instead of dragging tons of books with you.
The downside is I hate reading on a computer. The kindles does not read PDFs well though I have been told that that the nook fully supports PDFs though I don't know anyone who has one who can confirm this.
