I think the problem is more that budgets don't take into account for enough integration testing, packaging, or automated patching to support enterprise environments.

There was a time when there were fewer threats to Internet based infrastructures and skipping patches didn't matter so much. Those times have passed and there are now significant threats arrayed against Internet systems. Additionally, commerce and government services are now predominately Internet based, putting far more at risk than before.

It's time to start putting more money into fixing the patching problem. I'm really tired of fixing broken systems that I was trying to patch. No good deed goes unpunished...
