I vaguely remember the TRS-80 Pocket Computer. Introduced in 1980, this little device was manufactured and marketed by the Tandy Corporation/Radio Shack. (Every shopping mall in the 1980s had a Radio Shack.) Science fiction author Isaac Asimov appeared in a series of marketing spots for the gadget.

I didn’t own a TRS-80 Pocket Computer, however. The MSRP was $169.95. In present-day money, that’s about $670—the cost of a base-model iPhone.
And of course, the TRS-80 Pocket Computer had a minimal functionality when compared to an iPhone. It couldn’t make phone calls, play music, or take photos. It couldn’t surf the Internet—which didn’t yet exist, anyway.
The TRS-80 Pocket Computer was programmable in BASIC (which couldn’t do much for the average consumer). Other than that, it was basically a glorified pocket calculator.
Herein lies an important realization about 1980s tech: it was very expensive, and it didn’t do much. Even if you could afford it, you usually concluded that you could do without it.
