Enough with placebo effect ML is a Lion with extra features the only thing you accomplish with these post is make apple richer all will run to install ML with the though is faster.

The os is also optimized. Not just Lion with added features.

I dont see any differences in graphic performance or speed.

This is great news... a friend (who is a developer) was telling me how ML was optimised so well that he can't believe how this is almost NEVER mentioned as a 'feature' in all the ML reviews.

He says this optimisation extends to iOS6 too since iOS6 is based on ML -- and iOS5 is based on Lion.

Good times ahead for those of us who got stuck with Lion pre-installed on their machines...!!!

But yeah... up to a 50% speed increase (maybe even more)?? WICKED!
