The comparison to railroads is apt. Railroads are still immensely important, even if people no longer romanticize them. Innovations in railroad technology are still very important. The financial difficulties railroads faced in the middle of the 20th century had more to do with the government promoting automobiles than with the superiority of cars and trucks. If Microsoft is the technology world's' equivalent of a railroad they are in a pretty good position -- they might not be the company everyone is talking about but they will be the company that everyone is dependent on.
