Well, we're here to spread the word: There's no lack of free software to be found online. Some of it is as powerful, if not more so, than the name-brand packages found on shelves at Best Buy for big bucks. By free, we mean you don't pay a dime except for what it costs to download and install the software. There are even times when you don't have to install anything, since there are a lot of great Web-based applications available these days.
