Like it or not...regardless of if it's right/wrong/cheaper/more expensive/stupid/intelligent Windows dominates the workplace, therefor it dominates the home. Make it work at work under a Windows managed enviroment and you'll wean more and more people off Windows in greater numbers.
I've also felt that people use windows at home because that is what they use at work. Alot of people learned their way around computers because of their work environment, they of course will want the same os at home.
That being said, it does make you sit up and notice when major retailers are offering cheap Linux pc's and selling out. That is something that prove my argument totally wrong. Why?
The business world doesn't want to move to Linux at the desk top because of the cost to educate(just one reasons). If they see the education occuring on it's own and crunch the numbers in savings as far as license fee's. They may start moving over. Your point about group policy and certain Linux os's being able to be included in group policies is a serious plus for them moving to the desk top.
Who knows... I use MS at home for my os. I prefer Unix to Linux at the server level(BSD). So, from my view point... I'll wait and see. If I get moved to a Linux desktop at work, I probably will move to the same at home.
