Well, at least not in a rigorous way.  People compare Win and Linux 
performance all the time, but it's never a real head to head 
comparison with comparable and controlled environments and configurations.

However, that's the whole "benchmarking magic" argument...

Stability is important to sales, especially in a server environment and

And likewise, WinXP on the desktop.  A company with 20,000 WinXP 
desktops cannot tolerate BSODs and mystery hangs on a significant 
fraction of those desktops at any frequency.  When your call center 
operators are being timed to the second, the sysadmin folks know 
INSTANTLY when there are problems.

But, just as in the server application, the configurations are 
rigorously controlled and tested.  It's certainly not the usual home 
computer with umpty-five downloaded widgets, etc.

More like grains of sand being dribbled about the feet.

And, bizarre as it may seem, Goliath might change into a service 
provider via webservices running on some sort of serverfarm which 
could conceivably be anything.  Imagine.. paying a nickle per 
document page to use the WebServices version of MSWord with whatever 
browser you care to use.  Hey, we're willing to pay that for a 
photocopier, and it doesn't even do spell checking.

I think it's also to support the turnkey software vendors who need a 
platform with more compute crunch for their existing Windows 
application.  Think finite element models of one kind or another.  If 
your application costs $50K/seat, a kilobuck or two for an OS isn't a big deal.

Mind you, MS does make a moving target here, and not necessarily to 
make it hard to do this, but just because they choose the way they 
want to go for their own interests. Kind of like fleas on a dog that 
decides to roll over.

But the difficulty of moving between Windows and *nix compared to 
among *nix is more like the difference between translating between 
German and English vs translating between English dialects.  There's 
common roots, and the grammar is similar, for the former, but the 
latter is mostly a matter of vocabulary and pronounciation.

It is further complicated by the fact that unlike in the 
language/dialect case, the two OSes (and their corresponding 
development models and environments) are both changing, windows more 
rapidly than *nix for the most part.
