Reviews for the Lenovo Yoga Book 9i 2-in-1 Dual Screen
86.6% Double trouble: Lenovo Yoga Book 9i 2-in-1 Dual Screen OLED convertible review | Notebookcheck
We’ve all seen the dual-screen Asus ZenBook and VivoBook laptops, but Lenovo is taking it one step further by replacing the keyboard and clickpad altogether with a 13.3-inch OLED touchscreen. It works for the most part if you can deal with the limited customization options.
80% Lenovo Yoga Book 9i review: Dual-screen done right
Source: Tom’s Guide 
The Lenovo Yoga Book 9i is an intriguing device due to its unique dual-screen design, and its multitasking capabilities are ideal for folks with large workloads. If you’re like me and have a dual-screen setup at home, the ability to have such usage while outdoors can’t be understated. For some, the Yoga Book 9i could be a huge game-changer. Though exceptional, the Yoga Book 9i is admittedly expensive. If its price is too steep or you find the dual-screen design gimmicky, the $1,399 Lenovo Yoga 9i Gen 8 is a great 2-in-1 laptop worth considering. The $1,399 Samsung Galaxy Book 3 Pro 360 is also a decent alternative for those invested in the Samsung ecosystem. Price aside, the Lenovo Yoga Book 9i comes with my strongest recommendation for those who want a simple and portable dual-screen setup
