I don't remember any recent discussion of free PDF software alternatives for a Windows or Linux computer, so maybe it's time to stir up the pot.
For Windows, there is
Adobe Reader,
Digital Editions that also reads ePub documents, and the program that I've been using...
Foxit.
Are there any other really solid (and preferably lightweight) PDF readers out there that we should be considering? What's your favorite?
And for you Linux folks... what do you recommend? (Please be sure to indicate which OS you are discussing!)
