Actually, there is one reasonable scenario in which DOS might become widely
used once again. Although mainframes are not your forte, you may remember
IBM's VM/CMS offering. At the time, the economics favored running as many
users as possible in on a single physical machine, most of whom were doing
single task per user sorts of things. The VM component provided each user
with a separate virtual machine, and CMS provided an easy to use, single
user, operating system.

Of course, as the cost of hardware came down, individual personal computers
replaced the virtual machines, and PC-DOS became the CMS for this
environment.

However, microcomputers have now become so powerful that virtualization
is now the latest buzzword in the pc marketplace. Of course, the current
motivation for this is the ability to run Windows, Linux, and the new
Intel based MAC OS concurrently on a single machine. Nevertheless, once
such systems become common, the industry might find advantages to running
a number of single tasking applications, each in its own DOS virtual
machine.
