Depends on what you mean by "worth it" :) I develop applications (c) on AIX and it is a bit different, I find it rather close to the BSDs. There are minor oddities, but I think it is rather good, and I personally like it. As time goes forward, I think RHEL is going to be the direction. It is a bit sad to see these proprietary UNIXs fall by the wayside, but most of the reason is their fault for the restrictive licenses they have.
