On trial: Is Mac OS X half-baked?
Author: JT Smith
From Upside.com: "It is perhaps not surprising then, that OS X is more than a little retro: Jobs and Co. layered an admittedly new polish on top of a late 1980s NeXT interface, which is built on the early '80s Mach microkernel, itself steeped heavily in early 1970s Berkeley Unix. In other words, OS X's ballyhooed Unix underpinning dates back more than three decades."
