The ASUS Zenbook Duo is more affordable and quite portable with a unique dual-screen feature, suitable for general multitasking and productivity with moderate performance in 3D tasks. It has a decent battery life, making it good for on-the-go use. On the other hand, the Dell Alienware m18 R1 commands a higher price but delivers exceptional performance for gaming, engineering, and intensive 3D or machine learning tasks, thanks to its high-end components and ample storage. However, it's heavier and has shorter battery life, limiting its portability. If budget and mobility are priorities, go for ASUS, but for top-tier performance in demanding applications, the Dell might be worth the extra cost. 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."

"Dell's Alienware m18 delivers on its promises: This is a large, powerful gaming laptop with the premium flair and feel you expect from an expensive purchase. The drawbacks are really the price and battery life, which in context are reasonable. (We'd also like to see more ports on the laptop's sides.) This price tier exists for deep-pocketed enthusiasts, and if you’re considering anything in this range, the m18 isn’t an outlier. For the majority of shoppers, of course, all of these mighty 18-inch systems are likely too expensive."
