Been using it on a fully loaded macbook air. Completely anecdotal but I think my boot times are faster. But my encryption seems slower. Safari is wayyy more stable and faster. Messages is integrated better and love Notifications!

Launchpad is way smoother imho.

Does Messages work through a proxy yet? That was driving me nuts when I was playing with it in beta.

Is Mission Control any faster in switching spaces? It's incredibly annoying to wait 2-3 seconds to switch spaces, every, time. Especially since it was configurable in Snow Leopard.

This really bothers me too on an air where I'm switching back and forth from fullscreened terminal to browser constantly. Fine, it looks an feels quite cool when combined with a swipe, but it's really sluggish when you switch with assigned keys instead..

On Lion machines, using the keyboard shortcuts (ctrl/cmd+1/2/3/4), switching spaces is well under a second (my guess would be 500~750ms). From MC (which takes again less than a second to enter), entering a space is more in the 750~1000ms range but still, I don't know where you get that 2~3s figure.

This may help, although I found too fast an animation makes me dizzy after a while.

That's the mission control expose animation, I know of that and use it. I want the four finger swipe sped up. I don't know the absolute numbering of my spaces, it's a relative association for me.

Ok, I never use that one. Sadly it seems that for the sake of consistency with the physical world this animation is tied to the movement of your hand (whereas the MC exposé swipe is a trigger).

One can set up "Move Left/Right a Space" shortcuts in the Keyboard prefpane. Same animation speed as the swipe, which feels ungodly slow.

I haven't tried the GM but on DP4 it felt like the animation takes even longer than on Lion. It moves at the same speed but the 'settling' time when it's slowing down is much, much longer. I'm talking half-a-second-longer longer.

Being unable to cycle through windows with tab in exposé is what really hacks me off about Lion at the moment.
