As I've mentioned before, as a software developer I'm always happy to pay for good software, but that doesn't mean I don't appreciate finding good free tools.
My Dell Laptop didn't come with any 3rd party CD burning software and I wanted to burn an ISO image ... a quick google search brought me to http://www.freeisoburner.com/.
I downloaded the app, checked it for viruses and started it up. It was simple, didn't install unnecessary files to my computer, and successfully burned my Slax CD image.
5 stars for doing exactly what I needed and nothing more. If you're looking for a free application to burn ISO files - Free ISO burner is perfect.
