That's quite true. The only thing you don't have is serial access during the initial configuration such as installation or during the boot sequence. Usually, it isn't all that necessary to have the boot messages talking, but it is nice to have that capability if something goes wrong and it is time to start being a diagnostition. I also got on to slashdot.org and read a lot of the linux VS Windows thread. I am not sure if some of those folks are actually serious with some of their assumptions or are just jerking our chains to see what we do. Anyway, the one thing I have not heard anybody say is that a text-based interface is usable by everybody by one means or another. A so-called graphical interface must be modified for any other form of access. When blind people use Windows, it is only because there has been some progress in making it sort of behave like a command line interface. There just is not a good way to directly translate purely visual information in to anything else that works as well. There is an interesting experiment that Bell Labs did in 1951. I remember the year because it happens to be the year I was born so things like that kind of stand out. What they did was to build a rather clever voice synthesizer for that day out of a spinning wheel with bands of holes in it. When the wheel was spun at a certain rate, the holes raced past at different frequencies. A light shown through the holes and struck a photo cell like the kind used in film projectors to convert the wavy band of the film sound track to speech and music. By blocking or unblocking light from different bands of holes, the scientists could produce lots of musical tones of different pitches. The next neat thing they did was to record a human voice on a spectrograph which draws varying lines on a strip of film that correspond to all the constituent frequencies in the sound being recorded. In this case, it was a man saying "Never kill a snake with your bare hands." They took the film and used it to block and unblock the beams of light through the bands of holes on their sound generator. The bands of holes corresponded to the center frequencies of all the octave bands on the spectrograph machine. The result was a voice that sounds kind of like a DecTalk saying the recorded sentence very clearly. The spectrogram looks like strange light and dark bands on the film and means little to the eye except maybe that of an engineer, but it did cause the generator to produce pretty good speech. The scientists then tried to make speech of their own by manually painting spectrograms in a way that they thought would produce new words and voices. It never did anything but make weird noises. My whole point is that the easiest way for a person who is blind to do complex tasks on a computer is to use text. It may be that when tactile displays become dirt cheap and we can put our hands on a screen and feel shapes, we may actually get closer to using a GUI, but right now, we only use Windows when it can be bludgeoned in to behaving like a command line. Think about it. By the way, the only reason I remember the Bell Labs experiments is because they appeared in a Bell Telephone Hour special in the late fifties on television and I happened later to read about them while doing a report in Graduate school. My memory back to earlier times is probably no better than anybody else's. Just thought I had better throw that in.
