Sadly, you're living in a bubble.  As long as there are banks and very 
large commercial institutions, there will be legacy installations. 
Including t/r.  And OS/2.  And windows NT 3.51.  And FDDI and X.25 and 
every single legacy protocol, type of hardware and ancient operating system 
that ever existed.

Why do you think the Cisco 7500 only went EoS 3 years ago?
