Imagine if every Thursday your shoes exploded if you tied them the usual way. This happens to us all the time with computers, and nobody thinks of complaining.

An interface is humane if it is responsive to human needs and considerate of human frailties.

As far as the customer is concerned, the interface is the product.

Users do not care about what is inside the box, as long as the box does what they need done.

I am confident that we can do better than GUIs because the basic problem with them (and with the Linux and Unix interfaces) is that they ask a human being to do things that we know experimentally humans cannot do well. The question I asked myself is, given everything we know about how the human mind works, could we design a computer and computer software so that we can work with the least confusion and greatest efficiency?

I hate mice. The mouse involves you in arm motions that slow you down. I didn't want it on the Macintosh, but Jobs insisted. In those days, what he said went, good idea or not.

Once the product's task is known, design the interface first; then implement to the interface design.
