Even with all those definitive features, it's still a third-rate OS.
MulltiFinder was ahead of its time, but that was the last respectable OS
innovation (modulo VM), and that was ten years ago. Sys7 and Win95 are
almost at parity, but NT and Unix are still light-years ahead.
I agree 100% with the Byte analysis. But I wouldn't confuse user-level
features with OS excellence.
