What are the advantages and disadvantages of PDF ebooks over paper?

Advantages:

No mail delays - download it now.
Color illustrations
Point-and-click links to hints and answers
Text and pictures are resizable on your viewing screen.
Use a printer attached to your computer to print any pages you want to work on paper.

Disadvantages:

Heavily formatted pages sometimes display poorly on smaller Kindle and Nook screens.
Text does not reflow like it does in EPUB, AZW, and other ebook formats.
Writing answers on the screen kind of ruins it.
