I barely got an opportunity to try out Solaris/opensolaris (honestly I don’t remember which) before Oracle got involved. It gave me the impression of being a no nonsense, get shit done workstation OS. It was clean, it had enough frill that anyone could sit down in front of it and start working, but it wasn’t showy. I wasn’t a business person doing business things, and I was really just looking around for a good office suite on a stable OS that I could make it through college with. I really liked the “this is where work gets done” feel of it.
