> My first (childhood) computer was a 486 (DX I think?). Pentiums were already out, even PIIs maybe. The LEDs on the front (remember those?) said "100", but I was always suspicious of these, because my computer seemed a _lot_ slower (at playing games – what else) than my friend's 133MHz... But his was a Pentium(!), so I never got to the bottom of it.

A Pentium is much faster than a 486 at the same clock speed, so that shouldn't be surprising.
