The only UNIX system with a good applications universe I have ever owned was the AT&T UNIX-PC from 1985.
I actually had a licensed multiuser copy of real Microsoft Word on that system. On UNIX!
I think the MS Word license cost $450 in 1985.
AT&T UNIX System V release 2 with the 4.2 BSD virtual memory. And dynamically loadable device drivers.
This was a Motorola based workstation, not a PC clone.
You could even buy ORACLE for it. As well as INFORMIX. I think the ORACLE license was about a thousand dollars.
I ported Berkeley SPICE 3C1 to that system.
I ran Solaris on a dual Xeon Intel motherboard later for a few years and it was the same as Linux, poor quality applications for home PC use.
I ran Microsoft XP with the SFU Unix package on my IBM/Lenovo T60 laptop and that was good because it wasn't an emulator. Microsoft actually merged AT&T SVr4 UNIX into the guts of XP.
My favorite Linux is SUSE Enterprise Linux.
I have run ORACLE 10g Enterprise RAC on that.
It has a lot of the look and feel of AT&T UNIX.
But again the applications are disappointing in quality for home PC use.
So you're kind of forced to put up with Microsoft if you want a good home PC experience.
I have never liked Apple PCs except for the Mac IIfx. They are typically slow and the user interface is so frustrating that you feel like you want to just rip the top off so you can get to the guts of it.
The Mac IIfx was insanely fast but cost around $7,500 or so in 1992.
I'm sort of resigned to the fact that you have to put up with Microsoft Windows if you want a decent home PC experience.
