"business related apps"
What if that business-related app is a custom industrial control system that runs on XP and only XP? Changing OS is not an option due to the custom nature of the hardware (which also means it can't be virtualized, so VMs are not an option), and since the hardware's hugely expensive and still being amortized, you can't switch it out.
