The ROI of Open Source

The ROI of open-source software is a contentious issue. Several recent studies, conducted by Yankee Group, JupiterResearch, Forrester Research and others, have focused on the ROI of upgrading a Windows installation versus switching to Linux and have concluded that it is less expensive to stick with Windows. But the reports miss a critical point: Switching from Windows to Linux is the worst-case ROI scenario. After all, the new platform requires training and perhaps hiring new personnel-always expensive propositions-versus merely paying for licenses.
