"The Zenbook Pro 14 Duo OLED is a well-tuned instrument for content creators, excelling at a range of general office tasks as well as tasks that require a little more grunt like encoding and 3D rendering. The big attraction is the laptop’s dual displays. They’re the best ones we’ve used in an Asus Zenbook Duo laptop to date with a spate of year-on-year improvements that make the visuals more striking and the cross-screen integration easier than ever before."

"Notable qualities of the Inspiron 7420 2-in-1 include the 16:10 aspect ratio, strong hinges, 12th gen Intel CPU with optional GeForce MX graphics, and easy serviceability. Such features would typically cost hundreds of dollars more on higher-end alternatives from competing manufacturers. The value proposition is therefore relatively high for users looking to maximize bang for the buck."
