The thing that you seem not to get is "All Windows without hardware consolidation (aka VM's)" is the most expensive of options .... Windows is NOT the most expensive option on the desktop, I think Solaris/HP-UX,/AIX would be ... it certainly is NOT the cheapest, Linux is ... again, it comes as Windows Server Datacenter edition, then for desktop ... and is cheaper than Windows Pro+Office, since you only pay support and it has all the software you need, even more than you need ....
The thing is, it is by far the most expensive on server ... think about it ... the competition offers no Basic/Advanced/DataCenter variants ... with the competition, you get DataCenter for everything ... this coupled with VM's mean Windows Server offering is not even in the same league.... and then they even dare sucking in CALS, server software licenses (Exchange, SQL Server, Sharepoint etc) ... when in Linux/FreeBSD land, you only pay support, whatever you run on your server ...
I think you should ask Santa for a calculator ... you would be surprised.
Was it you playing sax in the street last Sunday ? You should be happy I threw 2 euro into your hat ...
