I actually just got XP Pro last week running on my primary PC. Admittedly I can not say from personal experience that DM support will not work on many PCs. I will say that when I got XP home a few years ago and upgraded my PC from 98 the dual monitor wasn’t happening.

I read all the PC tech help forums I could and put together the facts I have stated above. It could be a conspiracy to get people to get the more expensive OS but I doubt it.
The article you posted about the differences is very vague on the real tech concerns, it was written for a very non-tech user.

As far as dual monitor support, XP-Pro supports up to 10 monitors (I could find the specs but this is again from memory) XP home supports 3 maximum I believe.
They are different operating systems as far as support for hardware is concerned IMO.
