Ah, the arrow of truth. Much like wireless hotspots, I can envision a hotspot network of linux terminal servers set up by people that people just connect to with their diskless client where they can surf, maybe do a little open office.
The once mighty PC is seen as a threat, vulnerable to trojans and viruses that spread to other PCs across the network. The dominance of software licensing schemes further exacerbates this growing view that a business desktop PC is dangerous and burdensome.
Today we lock down these PCs, control them through a central IT group and call them "managed desktops." Ironically, and almost laughably, today the personal computer in business is nothing more than a storage of applications that require licensing schemes and are controlled by a central server.
