OS X 10.11 El Capitan: the Ars Technica review
 

Sadly no longer written by John Siracusa, but still a good read: Ars' Max OS X El Capitan review. Really, this is the first time in several years that iOS and OS X have felt like they've gotten (and needed) the same amount of attention from Apple - both get to spend a release in the slow lane as Apple puts its marketing muscle behind newer platforms like the Apple Watch and the new Apple TV. Like iOS 9 (and Mountain Lion, and Snow Leopard), El Capitan is about refinement. Yosemite's big statement was "This is what OS X looks like now." El Capitan's is a relatively meek "Hey, I have a couple neat tricks to show you."
