Apple's refreshed MacBook Air now shipping to giddy buyers

You know those spec-bumped MacBook Airs that were announced around a fortnight ago alongside those shiny (literally) new MacBooks / MacBook Pros? Yeah, well they're shipping. Reports filled with intense levels of joviality are beginning to spring up on Mac message boards the intarwebz over, and within them are proclamations of tracking number receipts. Sure, a new NVIDIA GeForce 9400M graphics system, a slightly speedier CPU and a mini DisplayPort are worth getting jazzed over, but try not to blow a cork while bottled up in that cube of yours, okay?
