Of course some apps stopped working, but those will all come in time.
Spotlight lags, my System Preferences won't open the Sound pane ....
Usually these kind of things imply a lot of cruft in your install that a clean install or archive/install would solve. Macports being broken is normal since that seems to happen with every major OS upgrade. But based on the rest of your post my guess is you have a pretty customized setup and because the OS was a major upgrade not everything went well.
As a developer and very heavy user of SL, while not everything is perfect, its a great release.
For those who complain that SL was supposed to be some polish only - while that's Apple's marketing, its not true. SL is a pretty big change to the underside of the OS. The kernel uses GCD instead of plain threads now - this in itself is a huge change to how stuff works. Everything is 64-bit which means that a lot of stuff has been optimized, polished, and as a side-effect - is new.
SL was tested heavily by Apple and devs. But because of the architecture, I find that old cruft affects it more than people realize. I found that until I updated a few key things I used they all broke badly.
The one bug that seems to be completely Apple's and completely irresponsible for Apple to let be is crashing in open/save dialogs. That's inexcusable. Now lets see if 10.6.1 helps with that.
