"Years ago, I took a class on computer user-interface
design. Some of my professor's words have stayed with me since
then. One characteristic of a user-friendly system, he told us, is
that it does what the user wants. In other words, the most
user-friendly system isn't necessarily the simplest one.
If you'd never seen a BMW (or a pick-your-favorite-car), you
might think that a horse is the best way to get where you're going:
it's easy to use, simple to maintain, and you might see some nice
scenery as you (slowly) reach your destination. So why would you
want a sophisticated automobile?"
