Windows support costs are hard to identify. We know who supports the mainframe; they work for mainframe IT. But Windows in each department is supported in his "spare time" by that bright computer whiz kid in that department, and he is on their payroll.
I don't believe the cost of supporting those desktop Windows systems should be included in any analysis of server vs. mainframe costs. It's unlikely that in a server to mainframe conversion those desktop systems will suddenly disappear. E-mail clients, spreadsheets, graphics packages and whatnot will still be in use on those desktops and require continued support. Heck, after the conversion at least some of those people are going to need 3270 session, and I don't think their employer is going to go out and buy new 3270 terminals. (Does anyone even make real 3270 terminals these days?) So "whatnot" will have to include 3270 emulators, as well.
