Parent article: Is Linux really losing market share to Windows? (Linux-Watch)

Yup, to a sales survey I can imagine the business I work for looks like

20-30 Windows desktops
10-20 Windows laptops
3-5 Mac laptops
1 Windows file & print server
100 or so generic 1U rack servers, no OS

So the fact that one laptop user runs Fedora, the Mac users often run Windows, and the generic
1U rack machines are all CentOS doesn't appear on the radar. But, the survey companies have
actually recognised this since the outset of their Linux coverage a decade or so ago. You will
see it mentioned in their full reports. It's just that it doesn't translate into a sentence
fragment for a magazine headline.

Of course most businesses probably own more desktops than servers, but there are going to be
more and more exceptions (Google may already be a very large and identifiable example...)

A better approximation would perhaps be calculable thus:

Total number of desktops = number of desktop CPUs sold  by intel + amd.
 (or, count motherboards).

Total number of Macs = number of machines sold by apple.

Total number of Windows machines = number that connect to windows update.

Total Linux = CPUs - (Macs + Windows).

That should probably give a decent-ish upper-bound estimate for Linux.

Execpt for everybody who's bought a laptop & junked XP to install linux.  Taxes work best when
it is more effort to avoid them than to just pony up.

Chips and counts

Total Linux = CPUs - (Macs + Windows).

That kind of approximation needs a lot of refinement: some machines sold by Apple contain Intel chips, and some of them run Linux (both with Intel and PowerPC chips).

After all chips are properly accounted for, only Microsoft can do the math: only they know how many machines connect to Windows Update. Even so, many machines are not connected to the internet, or have been decommissioned long ago. You have to estimate the percentages for each scenario, so it becomes grossly inaccurate even with Microsoft data. And even before *BSD fans come screaming at you.
