Well, I think I'll use Mavericks. Something really scares me about them introducing a new file system in their current yearly release cycle. HFS+ may suck, but I'd rather use that than a half-baked new one.
Aside from that, I don't really care for the other changes. I barely use iCloud, and I'd rather not have my files thrown around in the background. I also do not want to be blocked from opening applications I get from the internet.
