With good reason.

I'm peripherally involved with parts of the computational physics
community. The system I'm currently working with (when I'm not wasting
time reading posts on s.p.r.) has 2048 processors.

Windows does not support such a machine.

In the high-performance computing world, Unix in all its flavors is
currently the dominant OS; as far as I know, there is as yet no credible
version of Windows available for HP computing work.

Furthermore, much of the HP computing work is done remotely (you don't
stick a 2048 processor system under your desk, for example). In
consequence, X windows is also used heavily in such work. X support on
MS Windows is still not up to X on Unix systems, though it's gotten better.

So while it's certainly feasible to put Windows on your desktop and spend
all your work-time talking to Unix systems, it's also very common to use
Unix front-to-back when working in that environment.

FWIW I still run Quicken on MS Windows ('cause it doesn't run on Linux :-) )
