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)
