Recommending a portable business laptop has never been an issue. My answer: "Just buy the Lenovo ThinkPad X1 Carbon." It's that simple. Well, it was until Asus sent us the ExpertBook B9450, a featherweight 14-inch laptop with the longest battery life of any notebook we've ever tested.

Along with its epic endurance, this ultraportable enterprise machine has a slim yet durable chassis, a solid 1080p display and plenty of security features, including a fingerprint sensor and IR camera. Other standout additions include an illuminated number pad integrated into the touchpad and a light bar on the laptop's front edge.
