System 9.x
and before are
"something different" for me, a break from my mostly hardcore CLI
existence.
Yes, true. An OS I still miss, for all its instability and quirkiness.
I'd love to see a modern FOSS recreation, at least of the concept and
the style, even if it was binary-incompatible.
What do you feel is still missing from OS-X today? About the only thing I
can think of is the unique file system, where each file had a data and a
resource fork.
