Unix-based operating systems
Hello. I own a MacBook (black) running Leopard (Mac OS X 10.5.8), and I'm curious about a few things -- any help will be very, very much appreciated. I'm pretty much a newbie to Unix, although I have some very basic command-line skills with Mac OS X's Terminal. So while I know how to work the command-line to a certain degree, I have no idea about any of the various Unix-based OS's out there, and that's what I want to ask about. Here's a few questions:
1.) I think the answer to this is no, but I want to make sure -- is there just a Unix operating system? Could I go online, for example, and buy the Unix operating system? Is there a plain-old Unix, or are there only Unix-based operating systems like Linux and BSD and Solaris and whatnot?
2.) Like I mentioned, I have a MacBook. I am also about to buy a PC notebook very soon. I know Mac OS X has Unix at its core, but I would still like to have an actual Unix operating system installed on one of these two computers. I am a developer, and my primary use of this Unix OS will be for programming and development. Given this information, does anyone have any recommendation/advice/information as to which Unix-based OS might be best for me? Is there one (or some) that might be better than the others for me? I'm not concerned so much about price, and I would like a really good, high-end OS. I know many of these OS's have their own purposes and are different from one another, so I know it would be naive to say I want "the best" one, but I would like to know what the best options are for me in terms of high-end, Unix-based operating systems. I've done some research before I came here, but I don't know enough about a lot of the stuff I'm reading to get a good idea of what would be best for me, and I wanted to get the input of people who have real firsthand experience with this kind of thing.
3.) I don't want to do a Live-CD version or anything like that, so would it be better to install this OS on my MacBook or on the PC? Does it matter? Mac's have always been more stable in my experience, so I was thinking that it might handle formatting the hard disk (if that's necessary) better, especially since it's Unix-based to begin with. Would it be more efficient or better overall to partition the HD and install the OS on the Mac or the PC, if either?
Thank you very much in advance for your time and help. I really appreciated any information that anyone has time to give regarding the above questions. Thanks again!
