Serious investigations into UNIX and Windows

[Stefan [Swebase AB]]

Hi

I have tried searching for this but i only get reports made by students 
and private programmers, i trust a programmer more than a large 
corporation any day but to show a person i know and convince him i need 
some serious investigations made by large corporations into comparing 
BSD and Windows systems in various areas. I would love to get some links 
that some of you have in your bookmarks on this. The person i'm trying 
to convince is a hardcore MS fan so i need real evidence of why BSD is 
better than MS products in server environments.

Some friends of mine have told me that yahoo, msn and microsoft all use 
FreeBSD but until i can show him that and prove it to him that means 
nothing.
