I loved SunOS, Solaris, and OpenSolaris, but after the Oracle buyout all of the Sun equipment has been slowly replaced and has gone away for the most part, and with the important features being ported to other OSes like FreeBSD, there's not much of a real reason to use OpenSolaris or its babies. Having said that though, I'm put off by the name OpenIndiana, it just sounds really stupid to me, and I don't think I could ever install something like that without flat out denying it if anyone asked. It just makes me think "that's the best name you could come up with, huh? Not even anything remotely related to the Sun or stars or anything..." (I realise the origin comes from a project name, but sticking with it was a mistake, so in a sense I guess I should say "So, couldn't come up with anything at all?")
