ASUS Zenbook Duo review: The first dual-screen laptop worth buying

Almost every major PC maker has dabbled with the idea of a dual-screen laptop at some point. Way back in 2011, Acer released the Iconia 6120 sporting not one but two 14-inch displays. Then at CES 2017, Razer showed off Project Valerie which bumped the panel count to three before demoing something a bit less extravagant a year later in Project Linda. Fast forward to 2020, when Dell dazzled us with the Concept Duet. Even Apple gave the category a go on the old MacBook Pros with Touch Bars, only to reverse course and ditch them completely a couple of years ago.
