Not really, speaking as an IT leader at an F500 still running NT4.0 workstations and some Win98 desktops. Unsupported, isolated on VLANs to avoid infection, but still running. The same company is still mostly using Office 2003. If MS has 3rd party entanglement with VARs and SIs, Google has the same with developers & startups. I'm honestly not sure which would be worse for the economy if it disappeared.
