I'm not trying to hate on Lion. I will be upgrading of course.

For me I am excited for
1.) TRIM
2.) The new finder is growing on me
3.) Airdrop could be very useful at work
4.) Full screen apps have been cool

Cool stuff...

However can anyone comment on if preview 2 has better CPU and memory utilization.

Thanks. (Especially if you have a MacBook Air, we don't have a lot of resources to throw around)

Since the Macbook Air is Apple's newest computer product, I seriously doubt they will make an OS that cripple it. Don't worry, Lion will run a dream on it when it is released.

On the Apple site Lion is almost always shown on a Macbook Air, so of course it should run perfectly fine when the final build is released. I don't have Dev Preview 2 (or a Macbook Air), but I assume they've at least made it a bit better.
