Windows users may not be familiar with it because Adobe
charges a fortune for a pdf writer and M$ considered putting one into Vista, but
decided not to cut off a source of revenue for one of its partners. With Linux
pdf writing is built in. You can install either a pdf printer or write to file
as either pdf or postscript.
I write to pdfs all of the time. I use it for recipe cards, tips I find on the
net for computing or photography, and articles I want to read later. This is
something worth remembering, especially if you are environmentally conscious and
want to avoid using paper or if you want to manage your space using electronic
means.
