As an experiment, I examined their stats for the period before and after Google migrated its 10K employees to GNU/Linux back in 2010. The result was that 10K people swung the stats from a few percent to 88% in a community of 74K people (Mountain View, California). Even considering employees of Google and their families may have switched to GNU/Linux at home, the swing is far too large. The only conclusion I have is that NetApplications may be sampling only during business hours so that they measure mostly business usage which is locked in to M$'s office suite on their OS."
