Bill Joy, Creater or VI interview cirta 1984:
REVIEW: What is it that Interleaf offers you that EMACS doesn't?
JOY: I can just look at my screen, and when I print it off, it's the same as it looks on the screen. It is formatted, and I'm tired of using vi. I get really bored. There have been many nights when I've fallen asleep at the keyboard trying to make a release. At least now I can fall asleep with a mouse in my hand. I use the Xerox optica mouse instead of the other one because it is color coordinated with my office. Did you notice? I prefer the white mouse to the black mouse. You've got to have some fun, right?
This business of using the same editor for 10 years - it's like living in the same place for 10 years. None of us does it. Everyone moves once a year, right?
