Coming this Summer, the greatest thing to happen to your Mac. OS X Mountain Lion. Especially for all you hold-outs, who didn't buy 10.7 Lion. This is even more secure!

Innovation comes back to the Mac.. One question, what are the minimum system requirements for running these and the other awesome features? Seems like they wouldn't have to be much more powerful than an iPad2.
