Microsoft is touting a new "independent" study aimed at helping users make fact-based choices between operating systems. This time, the study was performed by Jupiter Research and commissioned by Microsoft. Jupiter says that Microsoft had no editorial control whatsoever over its results. Jupiter found that IT managers consider Microsoft to be the most interoperable vendor, from an application perspective. Meanwhile, Microsoft is continuing to take lumps for its program for making its communications protocols readily available to third parties seeking to make their software work with Windows. Whose "facts" do you buy?
