Sure - but do most orgs develop their own TCO's? Or do they go to th MS/Novell/IBM site and download their's and say, "look, this is what we need!".

I work is a pretty very place. we recently did a cost analysis for wheather we should go with Linux or MS for server deployement. Sure -- *IF* we were paying official stated MS prices as posted on their web site Linux would have won -- but MS sell us their server products for over 75% off their official posted prices. When that's happeneing, you can take the TCO and shove it. Welcome to big business.
