Re: I also watched this popular TV programme in the 1970's
The idea of minaturization in general was pretty common in the 50s. Pretty much anyone that read sci-fi in the 60s, 70s, or 80s could see stuff like the iDevices coming and probably imagined a number of their own that looked like "shameless Apple copies".
I thought up some "shameless Apple copies" of my own in the 80s. (Inspired by Asimov)
