Years ago, before the iPad even existed, there existed an unofficial Apple tablet called the Modbook that was essentially a MacBook with its keyboard gutted and a touchscreen replacement for stylus input. For reasons unknown, the Modbook returns, but this time it's more "Pro."

Apple's iOS mobile operating system gets more robust and full-featured with every update. And with Apple focusing on it so much, we're actually to the point where features are debuted on iOS and poor OS X has to wait for them to make the transition over.

Today's big unveiling of the new MacBook Air was overshadowed by an unveiling from 15 minutes previous. I speak, of course, of the new version of Mac OS X, that being 10.7 or "Lion." While some features seem like incremental upgrades, it represents a paradigm shift for computer operating systems — borrowing from the best parts of their children, mobile OSes.
