New ‘Power Nap’ :  Soem sort of  Hibernation mode ..  It won’t engage the fans,  compatible with 2nd Gen Airs and the new MacBook Pro.   Will not be on other MacBooks, though…

There’s also alot of  emphsis on Apple’s official site  regarding an upgraded cooling system that pulls pushes air more efficiantly and quiter. 

Nice to see Thunderbolt in there and a few USB3 ports too..  Not sure how well this  new cooling fan ducted air blaeds will work.. they really go in depth on the fact they bent the fan blades to get things happening…. they make it sound like the reached a Ureka moment in blade design.. bit like when someone decided to put a bend in the tooth brush.. how basic is that

No Disc Drive !  no Dvd or Hard Drive instead they’re resorting to Flash Drive only. 25gig or 512gig
