Greatest Thing Since CompuServe - The PDF Standard

I've been meeting to post this one for a few days. The San Jose Mercury News reported this week that Adobe Systems announced that they are offering PDF (Portable Document File) as a standard. Some may say "this is the greatest thing since sliced bread," but its actually the greatest thing since CompuServe released GIF (Graphics Interchange Format) in 1987. Does this mean that I can convert to PDF for free? How about editing PDFs? For better or worse, the outcome will be very interesting.
