A computer is like a bicycle for the mind

Interesting post at Presentation Zen looking at the way we use computers. An analogy that I can relate to:

does a personal laptop in the school function as a bicycle for the mind, amplifying the student's own capabilities and new knowledge or is it more like a car with pre-packaged formulas that allow the student to become soft in the head while appearing to really go places?

Is a computer like a bicycle for the mind?
