Based on this review alone: buy it if you care about extremely lightweight at 990 grams — just accept hinge does not allow the screen to open flat to 180 degrees.
The reviewer concludes that the Asus ExpertBook Ultra is a business laptop with incredible durability and fast performance. It combines a super lightweight and thin design with robust features, excellent display quality, and impressive AI capabilities, making it a highly capable flagship device.
This review provides an in-depth look at the ASUS ExpertBook Ultra, focusing on its durability, compact design, display quality, performance, battery life, and unique AI features. The reviewer conducts various hands-on tests including a load-bearing test, water spill resistance, and performance benchmarks.
The ASUS ExpertBook Ultra is a highly recommended flagship business laptop, delivering exceptional durability and premium features in an ultra-compact design. It survived a 95kg weight test and a water spill on its keyboard, demonstrating its military-grade build and scratch-resistant nano-ceramic chassis. The powerful Intel Core Ultra X7 processor and integrated Intel Arc B390 GPU provide strong performance, though its hinge prevents the screen from opening flat 180 degrees. If you are a business professional requiring a lightweight, ultra-durable, and secure laptop with top-tier performance and a stunning display, this device is an excellent choice. However, if a 180-degree screen hinge is critical for your workflow, you might need to consider other options.
