Well, we already knew, didn't we? Open Source is good.
Now you can see in this small article that a study made by Gartner is showing more and more adoption of Open Source and that CIOs are happy with it.
Clearly, CIOs are not very much on the risky side of life, so whoever decide to adopt Open Source long ago has been benefiting from this attributes that now everybody is starting to accept.
Congratulations to the disruptive CIOs... and for the others, what are you waiting for?
