Re: you pay 7 bucks for a coffee?
"Most every Linux deployment to replace Windows has come with higher initial support costs."
We've been running a mixed environment for nearly 20 years
80% of the desktop support load is generated by windows (and MS services such as live.outlook.com) despite only being 15-20% of the fleet.
On servers, the 2 windows servers (software which can't be ported) generate about half as much support load as the rest of the fleet combined (30-odd systems)
Windows requires a disproportionate amount of support load.
