I have been intrested in Unix for a while now. I have used Debian as hobby for couple years (so I understand basics of command line in *nix, but of course it isn't much) and I work in Windows Deskside support (yeah, yeah I know ). Years ago I had a unix course in university (OS was sun os 5 without graphics, and it wasn't really very helpful course, but it gave an overview about stuff). I know my way in Windows command line, but I guess it isn't helpful in Unix.. So basically I am almost-virgin with Unix.

I work for company with offers a lots of online courses (and other kind of courses) for IBM AIX. So from my employer I could get a whole lot knowledge about AIX, BUT of course I wouldn't get my own AIX at home to try and I couldn't use it at work either. Even if I could go to class room course to try it, it wouldn't be same than learning at home. So I was wondering that should I still go for AIX and use some free unix-distro (System V of course) at home (any suggestions?) or should I just focus on some free bsd all together and forget whole AIX and system V?

Thanks a million if somebody bothers to give an opinion about this dilemma :P
