The ASUS ZenBook Pro Duo 15 is ideal for high-performance tasks like 3D modeling, machine learning, or gaming, thanks to its robust processor, top-tier graphics, and ample memory and storage. The OLED display is vibrant and it has a unique dual-screen design that can boost productivity in creative and multitasking workflows. However, its higher price, sizable weight, and moderate battery life make it less suitable for frequent travel. The LG Ultra 13 is more portable, offering lighter weight, a compact form factor, and longer battery life at a lower cost. While it can handle general use and lighter engineering work effectively, its integrated graphics and processor aren't suited for the most intensive tasks, and it has less memory and storage space. Choose the LG if portability and cost are priorities, or the ASUS for the most demanding applications and a superior display experience. Give Feedback

PCWorld

Jared Newman | August 2021
"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."

CNET

Joshua Goldman | April 2017
"The 13.3-inch LG Gram is a fine fit if you need to travel as light as possible for as long as possible without spending a fortune to do it. It might not be particularly sturdy or have an eye-catching design and its webcam is less than ideal, but with its sharp touch display, comfortable backlit keyboard, responsive touchpad and a fingerprint reader for extra security, the Gram makes a respectible everyday laptop for business or school work."
