OS X 10.9 Mavericks preview: faster, smarter, and leather-free

The 10th version of OS X, Mavericks, felt like an afterthought in the midst of Apple’s radical overhaul of its mobile operating system. In this case, rather than completely overhaul the look and feel of the entire platform, Apple has instead picked its spots, removing and adding features in particular places while all the while tuning for performance and efficiency throughout. I’ve been testing a very early version of Mavericks (it’s due out this fall) on a 13-inch MacBook Pro with Retina display, and I appreciate what Apple’s done here: it’s systematically fixing what was broken, without tampering with the parts it got right.
