The UNIX family, originally developed by AT&T, and its various derivatives, that is clearly what most people mean when they refer to “Unix”. Linux, like the Minix clone which also came from Europe, are completely separate families with different originators, and different derivatives.

The NeXT systems were by far the nicest workstation or desktop computers I had ever seen. They were better than Windows 95 systems about 5 years before Windows 95. The problem was distribution, the same problem Apple has today. There's just not enough good to go around in this world, sometimes, as a Linux box with an OSX skin is nowhere near the same O/S.

I'm not so sure. Most people I know have the idea that if it acts like UNIX they can call it a UNIX. Your definition also makes OS X not UNIX, which I think we both agree is UNIX. I think who owns the rights makes the rules, so only four operating systems get to be called UNIX. The rest are "UNIX-like" or "POSIX-compliant."

At least now you appear to be disagreeing with the charlatans who say Linux has ripped-off AT&T UNIX code.

I know some people in academia who still use them. Awesome machines, the WWW was invented on one because current proprietary text repository systems had onorous licensing.
