Heres a fairly long but pretty good intro to the new OS..
They even found a Steve Jobs clone and put him in a black T shirt..
I havent been a fan of the Mac really.. Tho it does look simple and smooth, some of the features in this OS look desirable and the simplicity is appealing, also the iPhone like browsing is funny, first the phone now the desktop.
Apple - Mac OS X Leopard - Guided Tour - Medium
I will see if this can be hacked to run on open hardware and give it a play... Would love to see unix devs work on ther desktop and UI experience to do what apple has done.
