Touted as Asus’s answer to the MacBook Pro, the ASUS ExpertBook is an extremely impressive device that matches a lot of Apple’s best tricks, and even exceeds them. The primary area the ExpertBook outpaces the Macbook Pro is in battery life. With a touted 24 hours of battery life possible, the ASUS blows the Mac away. But battery life isn’t the only thing to pay attention to here. An i-7 processor, 512GB SSD, and 16 GB of ram are all stored in a military-grade frame that protects against drops, shocks and vibrations.
