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."
