The ASUS Zenbook Duo 14 is a versatile choice for those who prioritize portability and a unique dual-screen experience, making it great for multitasking and creative work. It's lightweight and has a good battery life, suitable for general use and light engineering tasks with its capable processor and ample RAM. However, its gaming and 3D performance is limited by the integrated GPU, and the screen, while touch-enabled, has a standard refresh rate and resolution. On the other hand, the Lenovo Yoga Pro 9i is a powerhouse designed for users who need high performance for demanding tasks like gaming, 3D rendering, and machine learning, thanks to its discrete RTX GPU and higher RAM capacity. The Mini LED display offers superior color accuracy and brightness, with a higher resolution and refresh rate, which is excellent for professionals and enthusiasts who require a top-tier visual experience. It's also well-suited for engineering tasks with its high-performance CPU. However, it's heavier, more expensive, and has a shorter battery life compared to the ASUS. In summary, choose the ASUS Zenbook Duo 14 for its portability and innovative design if you're focused on general use with some light professional work. Opt for the Lenovo Yoga Pro 9i if you need a high-performance machine with a superior display for intensive tasks, accepting that it's less portable and costs more. 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."
