I've updated to Mavericks about a week ago, just before attending a conference, and I've had a fair share of problems, though it seems that (based on Google Searches) I'm in the minority with the main issue: I can't use tethering with my iPhone anymore. Wireless or wired tethering will setup just fine, and I can even ping hosts on the internet, but domain name resolution fails. I've tried all kinds of things (like adding the 8.8.8.8 server, or running Linux in a VM to see if it works fine in there) but somehow as soon as I am tethered, my Macbook Air can't resolve domain names anymore and using the internet is effectively useless. The other issue that I've had is that the system froze when I connected it via thunderbolt to a beamer. However, apart from that I'm getting longer battery life (from ~3 hours up to ~4.5 hours) and I like the OS. I guess bugs as the above are normal with OSX point releases. I still remember the pain when I ran Leopard.
