So far I've found that flash doesn't seem to work anymore, despite being the latest version. Also, I still have the old "Roll 'em up" pinball game, played fine under Ubuntu 9.04, gets choppy at times under 9.10.

I was almost convinced that there was a DNS problem, but it just so happens that my ISP decided to start sucking again right after the upgrade.

Now if you're using zfs on Mac OS, you can't complain if it loses your data. You already knew it was forked.
