I remember a moment from 1994 or so. I was using a friend's machine, which was running X on top of Linux. It was some model of 486. I had some image viewing windows open (xv program), and was editing a complex figure in XFig, and had some audio playing.

I was thinking, "man, this is nicely responsive and usable; how much RAM is in this thing?"

I drop to the shell to run "free" ... 6 megs!

Remembering these things is important, kind of like remembering rivers full of fish, frozen polar ice caps, or the song of an extinct bird.
