When I moved to my last employer in 1991, the technology was X Windows terminals connected to a Sun or HP server. All the software was on the server. The X Windows terminal was essentially a dedicated screen/mouse/keyboard to render a GUI environment...much like a generic browser in the current day. It sounds like the industry is moving back toward the 1991 model of having everything on the server with a generic GUI platform at the user end.
It hearkens back to the mainframe systems of the 70s.
My wife worked for a thin client manufacturer back in the 90s. Network Computing Devices (they were in Mountain View).
She got a duffle bag from them that I use as a range bag to this day.
