Maybe if you're buying widgets, but not services. Just like you may be ok with buying a car from a person who doesn't understand the value of his product, but would be more leery of hiring an accountant who didn't understand the value of his services. SaaS solutions are truly a service in this regard.
I guess I'm thinking of things like "Internet companies who don't realize that they're providing SLA-ed synchronous links with their IP video-conferencing service." They're selling you one thing, but you're getting most of the benefit from a part of it they don't even realize is worth anything.
