When choosing between the ASUS Zenbook Duo 14 and the Lenovo ThinkBook 13x, consider the ASUS for its unique dual-screen feature which may enhance multitasking and productivity, especially if you're into creative work or need additional screen real estate. It might also offer more value if you find it at a lower price point. However, the Lenovo is generally more lightweight and has a sleeker design, making it a better option for those who prioritize portability and a more traditional laptop experience. Additionally, if battery life is crucial for your day-to-day activities, you might find the Lenovo more suitable as dual-screen laptops often consume more power. Give Feedback

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."
