yeah, I agree. I think most places will at least keep it until the existing contract comes time for renegotiation and most will probably keep using cs.

It's far easier for IT departments to just keep using it than it is to switch and managers will complain about "the cost of migrating" and "the time to evaluate and test a new solution" or "other products don't have feature X that we need" (even when they don't need that feature, but THINK they do).
