I tried OpenSolaris because I do things like that, but I didn't quite get the hang of it.
It may be a proper Unix in the species sense, but that makes it almost, but not entirely, quite unlike Linux (my first love).
From what I've heard around the 'net, the system is quite nice, but I couldn't do anything advanced with it. Not that it couldn't
, I was just unfamiliar with the toolset.
That being said, I have no idea what Oracle plans to do, but I seriously don't think they have what it takes to pitch for OpenSolaris in the already chaotic Desktop arena. I think it might be worth their while to re-tool Sparc with a heavy dose of R&D, hopefully resulting in a premier platform upon which they can then push OpenSolaris as the workstation/server brains. That bundled with VirtualBox might make for a mighty platform indeed.
As far as OpenOffice is concerned, there's too much momentum behind it to stop now. Oracle will either embrace it as a precious connection with the OSS community or they'll let it off the Sun leash so they can concentrate on other things. Same with MySQL.
Then again, it's entirely possible that I am completely clueless
