I remember as a kid seeing a neighbor showing off his LaserDisc and at the time thinking "This is really cool, but we just got rid of records.... surely this can be done better and soon."

Soon wasn't very soon, but it was certainly one of those very capable, very cool, and yet tangibly not exactly what it could be type of technologies.

It's interesting how sometimes there's tech that absolutely is very cool and yet seems to just not quite be there just yet.
