As I prepare a full review of this 10.9-inch 2-in-1 ChromeOS based device I need to put something into perspective. I haven’t fully tested an ultra-mobile PC for over 6 years. I’m going to need some time to re-base my expectations because this Lenovo Duet 3 just seems too good. Update: I am testing the new, 2024 Duet Gen 9.
