Why computers are hard to use (part two)

Taking off my researcher hat for a moment: the real reason computers are difficult to use is simply that they are very, very, very complicated. No one expects a F-22 fighter jet to be easy to use, what makes a home computer any different (expect for the price, of course)? (note: the F-22's computer system performance is comparably to a high-end PC, but the plane costs one-hundred thousand times more)

The chips at the heart of modern PCs contain around 50 million transistors and an advanced operating system, like Windows XP, that runs on these chips took 100 million man-hours to create. The computers we use today are the most complicated machines humans have ever created (at least in the last 5000 years of history that we currently have access to). If something is so complicated we should not be astonished it is difficult to use. Quite the contrary, it is amazing that we can do anything at all with them without requiring years of study and training.
