If you've never tried open source software, you might think that free applications couldn't possibly be as good as those you pay for. This list might change your mind.
Nearly two years ago, we put together a list of 75 Open Source Tools to Replace Apps You Use Every Day. This year, we made that list a little longer, edited out some of the projects that are no longer actively maintained, updated our descriptions and added some newer projects.
On this list, you'll find a mix of apps for home users, schools, small businesses and enterprises. These applications are all noteworthy for their ease of use and overall quality. In fact, you might even find some that are arguably better than their commercial counterparts.
If you know of other open source projects that you think should be on the list the next time we do an update, feel free to make a suggestion in the comments section below.
