I’m becoming very fond of PDFs for my gaming hobby. Now, I love hardcopy, there’s no doubt of that. However, I’m finding it harder and harder to store stuff. So, PDF for the magazines? Fantastic!
The other aspect of this is the rulebooks. I got very attached to the d20 SRD, but access to the rulebooks is even better. I bought the 4e MM pdf some time ago. This week, finding my books were at home and I wanted to answer questions at work, I bought the DMG and PHB as well.
(Yes, the D&D Compendium is useful, but I often need answers that aren’t in that part of the book).
At some point, I’m going to need a laptop so I can take these books to the actual gaming table. That’d be nice, but for preparation and suchlike, not needing to lug around all the books from place to place is good.
