I think one of the interesting things is that vi is really a mode-based editor.

Document preparation systems will also require large screen displays.

I was surprised about vi going in, though, I didn't know it was in System V.

I wish we hadn't used all the keys on the keyboard.

I got tired of people complaining that it was too hard to use UNIX because the editor was too complicated.

You can't solve a problem with the management of technology with more technology.

There are always more smart people outside your company than within it.
