Lenovo’s dual-screen Yoga Book 9i also gets 14-inch screens, which catch it up in size to the Asus ZenBook Duo. The Yoga Book screens have a 2.8K resolution (2880 x 1800) at 120Hz per display, and they’re also brighter now at 750 nits versus 400 nits on the previous model.

The Lenovo Yoga Slim 9i hides a 32-megapixel webcam under its OLED screen. The updated Yoga Book 9i steps up to 14-inch screens with a bitter battery. And Intel's Lunar Lake powers the lineup.

Lenovo launched several Yoga laptop PCs at CES 2025, complete with a larger version of its Yoga Book 9i 14 and several additional laptops built around Intel's Lunar Lake or Core Ultra 200-series chips.
