Lenovo's Yoga 3 Pro notebook is thin, it's transformable, and it would appear to be Microsoft's newest favored son as it does battle with the MacBook Air in Microsoft's newest TV ad spot. This device is thinner than the MacBook Air. It's able to bend backwards far enough to turn itself into a tablet. It's got a touchscreen. It's also very similar looking to the MacBook Air from afar - but they really couldn't be more difference, when it comes down to it.
