Haven't tried to do that (doesn't sound like a particularly mainstream
issue) but I can and do run Virtual PC on my Macs for just about any PC
program that I need,

Can't run that one and thats the one I need to run.

Can
you run *any* OS X apps on your Win PC?

Do I need to run any OS-X apps on my PC?

Nope.

Frankly, your comment above is tantamount to my saying I can run a
Mac-only program and you can't.

You recommended that we XP users switch to OS-X. I am just pointing out that
for me to do so would be foolish, I couldn't run the apps I need to run.
