If you are seeking a laptop with higher performance for tasks like 3D rendering or engineering, the ASUS Zenbook Duo, with its up-to-date processor, improved graphics, and higher resolution display with touch support might be worth the extra cost. Keep in mind this laptop's heavier weight and shorter battery life if portability is important to you. On the other hand, the Dell Latitude 14 7490, while less powerful, offers longer battery life, is lighter, making it more suitable for general use and easy to carry around. The Dell's lower price also makes it a more budget-friendly option. Consider the ASUS if your work demands better performance and you're okay with a less portable device; choose the Dell if you prioritize long battery life, portability, and lower cost over cutting-edge specs.

Allen Ngo | May 2020
"The Asus ZenBook Duo's second screen is like the Apple Touch Bar, but better. Most would agree that having two screens instead of one can really boost productivity and the ZenBook Duo is no different in this regard. It's tough going back to just one screen after becoming accustomed to spacious dual-screen setups. For a laptop form factor, however, users will have to accept some compromises. Firstly, weight is the most obvious drawback as the system is several hundred grams heavier than a regular ZenBook 14. Additionally, colors on the second screen will not be as vivid as the main display."

"The Dell Latitude 7490's got the speed you need (and then some), a keyboard that's comfortable enough for writing all day long and a battery that supports a full 8-hour workday. If only the display were brighter and it managed heat better. If you need every minute of battery life you can get, the extended-battery version of the Lenovo ThinkPad T480 lasts 8 hours longer than the Latitude 7490, but its display is much less colorful."
