But I hear you - I get asked all the time, "but
what's it _good_ for?"
I compare it to building ships in bottles - not a productive
activity, but an entertaining one. That explanation seems to deflect
most of the odd looks. Most.
I sometimes descrbie troubelshooting classic computers as being similar t
o solving corssword puzzles/sudoku/etc. It is a good way of keeping your
brain active.
