Or in the industrial sector: Milling machines running Windows 95/98 (fun times getting it to talk with windows 10 on the network) or working with floppies are still around: Those beasts are too expensive to not run until dead.

Ah, yeah the hardware probably won't still be running in 2107, but will be running in 2040.

Of course, if New York's subway controls are anything to go by, 2107 is pretty reasonable.
