Wow! As a nerd from another world I bow to the prowess of this sophstication. Even to my untrained eye, I see it is just nicer! super cool to understand!
p.s.
To all the people hating on why apple should focus elsewhere. I say BULL. Of course a trillion dollar company should focus elsewhere, but it has enough money to focus HERE too. And it should.
We love our apple products becuase of the dozens of details we couldn't even articulate w/o some Jedi like Brad to explain it to us. It is not like that RAN OUT OF MONEY becuse they focused too much on design... so quit your hating ;-)
