Well it's about damn time the MacBook grew up. For years now, many of us OS X devotees have peered over the fence with envious eyes as Windows machines were given far more portable form-factors. Lenovo has been leading the pack in svelteness, and Microsoft's Surface Pro 3 has been appealing with its detachable keyboard, but at the end of the day Windows simply doesn't do it for me. The arrival of the new MacBook, however, meant those days of coveting notebooks could be long gone, with Apple taking the proven design of the MacBook Air and cutting out every last scrap of excess until - for the most part - only the features that matter remain. That's the theory, at least; I took the MacBook on the road to see if it was also the same in practice.
