This whole line of discussion cracks me up.
You don't have to do anything. I don't care how many people work for your company of how much it has invested in legacy MS software, whatever. It doesn't matter. The last time I checked, no one put a gun to your head and said "stick this damn CD in, and install it". Now, maybe there is an "economic" gun to your head, but guess what? That's YOUR problem, not mine, not anyone else's and certainly not Microsoft's. So your buisness is shackled to Microsoft? Sucks to you then, I guess. The fact of the matter is, your buisness is still profitable, otherwise you wouldn't be in buisness very long, would you?. Now, if your point of contention is that your buisness would be more profitable (productive, easier to manage, taller, or more fun to take on dates) without Microsoft, then I recommend you find another software company.
Can't? Well, then write your own.
Can't? Well, then we're back at square one. Now, who's fault is that? Mine? George Bush's? Angelina Jolie's? I'd say it's YOURS.
The point is, you've chosen MS for a reason. That reason is probably one of the following:
1. MS makes the most sense (most likely economically).
2. MS is the only possibile choice.
Now, when I go to dinner late at night, I usually end up at Jack in the Box. Why? Because it's cheap. Why else? Because it's the ONLY PLACE OPEN AT FOUR IN THE MORNING. So, do I get to complain because of my lack of options? And does my complaining make any more options appear? Now, I'd bet that if I was a smart buisnessman, and saw a large market for people who eat late, maybe I might start a late night food place thingee. And maybe Jack in the Box would put a store right next to mine. And maybe they'd lower their prices and put me out of buisness. Now, that would be illegal. And bad. But, just about anything else is pretty much...well...
say it with me folks: your problem.
