Good luck installing a free distro on a mainframe or even a big workstation. Even when possible, like for ProLiant/HP Zseries or PowerPC/SPARC servers, you lose your warrenty if you do that, you can't have support when you need it. This is just not an option for most managers buying these things.
You don't lose your warranty. At best you might lose some OS support from the vendor, if they even have that, but anyone going this route would get support from the community, hiring a company with techs for that particular OS or having the support in-house.
Bullshit.
We bought hundreds of HP and IBM servers and workstation with no OS pre-installed and used our RedHat and Microsoft site licenses to install them - and we never, and let me make it absolutely clear, NEVER, had any issues with warranty.
I greatly doubt that big companies use pre-installed as opposed to rolling using their own server/workstation/desktop images - be that for Windows or Linux.

In some cases the server vendor owns the OS (IBM & Oracle). How much can we rely on the accuracy of the numbers they report?
Does this take into account systems sold with no OS? Many large companies would have site licenses / support contracts and would not necessarily order the server with an OS installed. Others may be using freely available Linux distro's, a BSD or something else.
Does anyone have any idea how IDC account for the above?
