Performance was flying in the 90s. The last 1-2 decades if you bought a top end computer it'd easily last you the decade before it started to drag behind average. 3 decades ago if you bought a computer it'd reach the same point in 2-3 years.

I.e. computing is cheap compared to the past, but it only makes it that much more painful we went from "it'll be so much faster soon!" to "at least it's cheaper than it used to be" and now to "oh wow, it's like the reverse 90s these last 2-3 years!".
