Just speaking as a cantankerous old cynic, I wonder how much of this is being driven by a real concern and how much is being driven by someone with an agenda to use a "more favored" product. I've been pushed even further in the latter direction, in general, when I learned from a person who was evaluating a new server that they had decided against it because "It's not made by MicroSoft." Not that it was too expensive. Or didn't do the job. Just that it was not by the "most favored" vendor.
