In 1982 I can understand the appeal. In 2017? Nope.
There is really no practical reason to own them form any technical imaginable standpoint. Anything released on them is inferior in quality to later releases. Everything released was chopped down for TV viewing and there are no wide screen versions. Most discs have mono sound, a few of the later ones were released or re-released with stereo sound.
I've been collecting up movie media for a long time. I'm sure it's some minor form of mental condition something along the lines of a sensitivity to ephemera.
Televisions and home media hit me in some soft spot. I collect old TV sets and outdated media formats and equipment.
CEDs I have a soft spot for because they were just so darn crappy and yet an amazing technical work of art. Also, the disc cases are cool with their movie poster art and they look good on a shelf.
Same thing with other media I collect. It puts a smile on my face to look over and see a laserdisc copy of Stuff Stephanie in the Incinerator, or beta cassette of Gymkata.
Maybe I'll start making youtube videos about the stuff. Could do a show about a guy who opened a video store in an old bomb shelter and accidentally survived the apocalypse, now all his customers are mutants and barbarians who never rewind the tapes.
