Link: Open Source Alternatives List
Opensource.com is a very useful site. Here’s a list of open source alternatives to some common applications. I have used many of these myself. I plan in the near future to talk about the differences between the commercial options and open source options. There are often excellent reasons to use the commercial options, for example, InDesign vs. Scribus. I have used both, and InDesign has a number of benefits. As a user, however, you need to evaluate whether you are going to use the additional features rather than just buying because it’s the accepted thing.
