Yes , quite frequently i might say so.
Next to the obvious Linux distro's with all their packages (Knoppix , Mandrake , Red Hat , Slackware ,Evil Entity , etc) that i sometime use , i very much like the freeware software.
Most of it comes with a better support method (community/forum) than professional products and your input is appreciated most of the times (except for some egocentric programmers). These two things combined make open source and freeware software a better thing than just a "bought license" and some manual nobody reads anyway.
Exact Audio Copy , Plextools , CdSpeed , Toast , LbreakOut2 , etc , etc. All fine products
