Two screens at the same time. That is the whole appeal of Lenovo’s Yoga Book 9i in a nutshell. The $1,999.99 9i, for the uninitiated, is a dual-screen clamshell touchscreen laptop that eschews the traditional keyboard deck for a second touchscreen on the bottom half. Lenovo has been experimenting with nontraditional laptop designs for years, from foldable ThinkPads to twisting laptops with E Ink displays and virtual keyboards, and it hasn’t always gone well. High prices, awkward software, and unconventional designs have kept them from really being anything you should buy. The Yoga Book 9i is not without some of those compromises. Having two screens at the same time is a very compelling pitch for a lot of people accustomed to working at a desk. The two 13.3-inch, 2880 x 1800 OLED panels with 16:10 aspect ratios light up and give you two equally sized Windows desktops to play with. They’re colourful and punchy like OLED screens should be, and the 400 nit peak brightness is plenty for most situations outside of direct sunlight. Happily, the screens are well colour-matched, too.
