> If they gave a free upgrade to Windows 7, they could pretend Vista doesn't exist and eliminate most of its support costs; simply tell all customers that Vista will not be supported because Windows 7 is free and is compatible. That sounds nice in theory. In practice there are many companies that change OS's very slowly as it cost alot of money and time to test internal apps and systems on each new OS. I'd bet that even if Windows 7 was free there would be a substantial client base that would still stick with Vista, XP and 2000 because they don't want to have to upgrade thousands of computers.
