Latest fourth-gen MacBook Air updated with Intel Core i7 processor and the new screaming-fast Thunderbolt port. I’m glad the backlit keyboard is back but the star of the show is of course OS X Lion. Apple says there are about 250 new features in this latest OS iteration but what you’ll probably notice most are Mission Control (Dashboard, Exposé and Spaces combined), some new multi-touch gestures, and the ability to run apps in full-screen. These are all brilliant and welcome improvements to an already fantastic OS. But here’s the thing — there’s nothing groundbreaking enough to warrant a must-have upgrade. And if you’re switching between different laptops running Snow Leopard and Lion, some gestures can be confusing and counter-intuitive and actually slow you down. My advice? Upgrade all your Macs to Lion and rewire your brain, or stick to Snow Leopard for now. You’re not missing out on much.
