Well, I'm aware of the "expense" part and have no issue with it. It's one more thing to think about.

I'm more puzzled with the day to day differences...

In software it's - just software: code quality, making new features, fixing bugs, deployments, etc. Here it's much less software, more hardware and mostly it's organization-wide processes involving IT. Is this doable for someone who's been dealing with 99% of software related issues? Can transition happen?
