Is there still a pure unix system out there for download?

Q. I have tried linux, windows, and mac os x. I am curious however to see what a unix operating system with GUI looks like. I have heard and read countless of articles of linux being based on the "rock solid" and "very stable" UNIX kernel. I want to get the "pure" unix operating system not linux. Does anyone have any information about why UNIX is gone?

A. Unix still exists, but is generally only installed on custome hardware and often won't run on anything else. Irix (SGI's unix flavor) is one example if this, as well as HP-UX and AIX by HP and IBM, respectively. You can try Open Solaris, which is Sun's unix OS. It runs on standard PCs. Ditto for OpenBSD.

which operating systems are belongs to UNIX?
Q. I want to learn C-language on UNIX operating system. But I don't know which operating systems are belongs to UNIX.

A. I think you'd benefit from reading about POSIX

What are the cons and prons of the following types of computer?
Q. - A Mac OS X with the latest software suite (Snow Leopard i think)
- A PC with the Unix operating system
- A PC with the latest version of the Windows OS (Windows 7)

I really need help with the first two since I have never used them before and a few links/websites would help.

A. Mac - overpriced, inferior hardware, you're locked into Apple hardware, anything other than running files takes knowledge of the Unix shell. There are no advantages.

Unix - you need a knowledge of Unix. No friendly wizards to do it for you. Same as a Mac. (Not surprising, since Mac OSX is FreeBSD, a Unix offshoot.)

Windows - easier to run for 99.99% of computer users. Disadvantage - ease of writing viruses for i, so the average computer user, not knowing how to not download viruses, downloads more of them.
