_I_ care about it... I had the manual for one when I was about 12.  I
learned digital logic on paper from it.  I always wanted one, but the
books were much easier to find than boxes.

Every once in a while, I entertain making one of my own, but haven't
ever come up with an inexpensive and robust plug/connector scheme.

That _is_ more interesting.  I am also curious to learn more.
