UNIX for Dummies Questions & Answers

I'm not sure that this has been asked (I did a quick search) but what is the more popular OS? Not your favorite but more on a business level. The versions would be Solaris, HP/UX, AIX, Linux (what ever version).

I would make a poll, but not sure how to.

Thanks.

Having grown tired of our software holding us hostage, Linux is slowly encroaching on our Windows boxes here. It powers most important things. We've got Windows left on the desktops, but you could practically replace their remaining usefulness with web appliances.

OS X is a king !

It entirely depends on the type of server and the industry of the company. For example, Sun is (was at least) extremely popular in the Telecom industry while IBM is the king of banking.

Linux is growing rapidly in popularity among small 1 or 2 processor servers. For big machines (8 procs on up) commercial unix dominates, with AIX probably the most popular and Solaris probably 2nd.

You could look up statistics from somebody like Gartner if you wanted to, or even cNet news.com tends to have articles about market shares and all that. But the main point is you can't really have a general number with much meaning too it, you need to know more about the environment to say which OS would be most popular or best.
