I didn't say I was waiting to be forced, I said I was waiting for a good business case.
For example, I have 12 users that have Vista on their laptops, it's there because they are recruiters, and these laptops are the same as the ones students can buy in the campus computer store, so the case can be made for them.
There is a difference between being forced and being prudent. I like Vista, it's on my laptop at home, but I'm not disrupting my users without a good reason.
