That's the thing, it was the most novel OS of the time.

Even the OS we use today are all based on some kind of Unix, except for Windows that trace their legacy to VMS through Windows NT.

BeOS on the other time was written from scratch in the 1990's.

Yeah, novel things are needed for innovation. Just see how much Linux and other modern unices have taken from plan 9. I made my comment because while I like some of the things (the filesystem, it being written in C++, and parts of the kernel) I still vastly prefer an actual unix or unix clone instead of something completely different with a posix-ish coat of paint
