Actually your post reminded me of a bookmark I had laying around quite a while about why Ernie Ball dumped microsoft. FTA:

...Humiliated by the experience, Ball told his IT department he wanted Microsoft products out of his business within six months. "I said, 'I don't care if we have to buy 10,000 abacuses,'" recalled Ball, who recently addressed the LinuxWorld trade show. "We won't do business with someone who treats us poorly."

...What I really thought is that you ought to treat people the way you want to be treated. I couldn't treat a customer the way Microsoft dealt with me...I went from being a pro-Microsoft guy to instantly being an anti-Microsoft guy...
