I suspect that at least with notebooks (it's not practical to buy parts and assemble your own) this is the case. There are some functions - BIOS upgrades, hardware/firmware upgrades etc. that linux simply can't perform, hardware vendors don't support it. So it's prudent to have a windows install "in the back of the closet" to cover such functions. I can get a copy of Ubuntu to install as dual boot for free. I cannot get a copy of Windows to install as dual boot for free, at least not legally. This seems like it'd skew usage stats though. Headline:
