Free and Excellent Software

Here's an article from ComputerWorld which lists a bunch of software (from email to Office suites to graphics to money to antivirus to....) which is mostly free (a few items offer enhancements for a bit of money, like generally $10 or so). What is very exciting about the items on the list, though, is not only the low price, but also that in many cases the free stuff outdoes the expensive stuff - now THAT'S something I can really appreciate!
