What about system updates.
* Graphics glitches
* 2 Monitor issues some people have at boot time (freezes at blue screen)
* Issues where background images dissapear when coming out of screensaver or sleep. (if you do a "killall Dock" in the terminal it comes back, but shouldn't have to do that)
* I'm sure there's general perfocmances that could be gained.
I'm all for new features, but I'm even more interested in under-the-hood, functionality, glitches, performance, etc...
* Graphics glitches
I hope Glitches are gone after this update - it was really annoying to restarting MBP in the middle of work.
