I must admit I found the proposed $60 price a bit shocking when I read the article. Surely there are free software solutions which do much the same thing. I believe Okular can do most of the things the article alluded to.

That's true, $60 would be too much for current set of features. But this is a supposed price for updated version, which will be released soon, which includes powerful PDF editing features as well (similar to those in Acrobat Pro, for example).
