I haven't talked about this, mostly because I hadn't visited the site yet, but the old Dynix "customer care" website is in the process of switching over to the Client Care Portal. This is a joint client care website for both Unicorn and Horizon. I assume it's in place to get ready for Symphony. But it has this great added benefit to any Horizon customer (and Unicorn customer, too, I imagine), which is that you get to see how Unicorn works (and thus how Horizon works). Unicorn uses "patch clusters" instead of what we just called "updates" in Horizon, and I can get overviews of various Unicorn modules and such. I can see known issues with Unicorn, read white papers about the modules, etc.
I mean, granted, its all basically marketing nonsense, or things that I could find out very easily if I solicited some brochures and whatnot, but since traditionally, Horizon and Unicorn users weren't allowed to connect at all through the company, its very nice to see the other side. I know, I know: I'm saying something nice about SirsiDynix! It feels weird to me, too.
