I don't think Dos is dead at all. Though it was not the reason why AmigaOS died in a commercial context.
I believe there are lots of places that Dos are still in use. Mostly that would be a scenario in were you still have specific machines that require a program that only runs on Dos. I am talking about industrial use. Regarding the AmigaOS, then it is in no way as simple as "Dos killed AmigaOS". That in it self are not true, as the commercial death of AmigaOS are linked to other factors and not operating system in it self. Yes, Doom runs on Dos. However it is not the OS that prevents original doom to run on 1993 AmigaOS. In this case, it is the lack of chunky gfx in Amiga and nothing else. Yes. Even Amiga's and AmigaOS are still in use in rare cases, to drive stuff like climate controlling in more than 10 different schools, controlled by one single Amiga at the same time. C64 are another example, as you can find it in a few auto repair shops, were it is controlling the machine for balancing wheel's for cars.
These examples does not really say, that old platforms and operating systems are dead and gone. If you can find a Novell Netware 3.10 Server some were, then the boot OS are still Dos. Yet another example that Dos is not dead.
Don't eat stuff off a 15 year old never cleaned cpu cooler.
Those cakes make you sick....
