MS-DOS still powers many more machines than the average person would think. Next time you head on down to the super market, take a look at the computers they use. I've spotted some 122-key Model M's there, as well as one in the farm equipment store in my town. I have also seen many check-out computers running MS-DOS at the super market. At the public library, there's a whole bunch of Model M's. And on most airlines, the computers rely on Windows 3.1.
