I’m really enjoying the advent of RPG ebooks. Unlike mainstream ebooks, where everything is distributed with some form of copy-protection, RPG companies seem to have standardized on unencrypted PDFs. Unfortunately, the major companies have yet to clue-in, although alot of their books are available on KaZaA. I found a decent article about the RPG PDF phenomenon. The author assumes that everyone will be printing out their purchased PDFs, which seems crazy to me, I use my laptop.
