UNIX for Advanced & Expert Users

I would like information about what users think of using aix 5.1.0.2. We are considering to use aix 5.1.0.2. Ik hope that there is anybody who can help me find some extra information.

a user will not be able to tell you the differance IMHO.

BUT

as a sys admin i use aix 4.3.3 and atho i am more proficient in solaris. aix has grown on me and has some great features. personaly i like there disk managment over solaris as far as out of the box goes.

i mean for the most part all unixes are essentially the same minus syntax.

I dont think a user will know the differnace between the two.

Well the situation is that we use 4.3.3 at the moment, but we will probably upgrade to 5.1.0.2 and now I need to know what the differences are between those two. It doesn't matter to me if the person who replyes is a user or a programmer of whatsoever.
I just would like to get some information about it. Or else if someone knows where I can find the extra information.

IBM has information on it's latest version on the web.

IBM AIX - look for the upgrade benefit pdf link.
