You may have seen it. Passengers arrive at the gate, are promptly ushered onto the plane which takes off flawlessly and explodes upon reaching cruising altitude. They wait and wait.
Passengers arrive at the gate, are handed a set of tools and a manual and a seat to install.
Once installed, passengers sit for a flawless flight. The fun thing about the joke is that it says as much about the person using the system as it does the system itself. Whether it's completely true is not as important as the insight it gives us about why people choose the systems they do. I find it instructive as it tells me that some users prefer that computers work well as tools, but that the tools not call attention to themselves. Despite their supposed differences, both Windows and Mac operating systems cater to this group.
