Unlike many people who cover computer history, I generally avoid talking about prices “adjusted for inflation” when discussing older products. For example, one of the products demonstrated in this next Computer Chronicles episode, the Zenith Z-181 portable computer, originally retailed for $2,399 in 1987. If you run that figure through an online inflation calculator, it will tell you that this is the equivalent of $5,395.60 in “purchasing power” in December 2022.

I see a couple of problems with talking about computer prices in these terms. First, a computer is not like a quart of milk or some other commodity that has remained relatively consistent in terms of quality over the years. The Z-181 had 640 KB or memory. The laptop I’m typing this post on right now–a roughly 10-year Dell Latitude E7240 that I paid about $250 for refurbished–has 8 GB. If you were to price both machines on a “per-kilobyte” basis, the old Dell is infinitely cheaper than the antique Zenith.

Although Paul Schindler’s commentary comes at the end of the episode just before “Random Access,” I thought I’d discuss his thoughts upfront this time as it helps provide some useful context for this early January 1985 episode, which is about portable computers. Schindler compared a portable computer to a portable sewing machine. With respect to the latter, he said it made more sense for most people just to carry a needle with them. Sure, you wouldn’t be able to do any fancy sewing with a needle, but you could do smaller jobs quickly.
