The new Macbook is $500 cheaper, now only weighs 1.5 pounds more, and has a faster CPU than the MBA, not to mention the better array of ports, the fancy new trackpad, and the better battery life. It's only .2 inches thicker at the MBA's thickest point. I'm not sure if I'd be buying an MBA today if I needed a new laptop. I still don't care about the MBA's "missing" optical drive though. What do other MBA owners think about the new Macbook?
