Randy: Of course today's computers are faster, and we expect them to do more. I am arguing that the increase in computational resources (processor speed, memory, disk size) has not been matched by software performance. This is especially true with programs such as word processors, where the I/O speed is glacial. Let's look at a comparison from the late 1980s. I had an AT&T Unix PC (PC7300, 3b1) with 1MB memory, a 20MB disk and a 68010 at 10MHz. My current computer running Linux has 1000x more memory, 5000x more disk and is 500x as fast. The Unix PC ran a full version of Unix System V with a graphical interface (but not X-Windows). I would not go back, but I do not think the performance of my current computer is 500x better.
