Like it or not, companies are set on making foldable PCs a thing. Asus' Zenbook 17 Fold OLED turned out to be one of 2022's most adventurous laptops, and Lenovo is planning its second foldable, the 16-inch ThinkPad X1 Fold for this spring. Assuming an operating system and apps that play well with the form factor, foldables excite multitaskers, workers, and creatives who can benefit from larger, yet still portable, display options, especially those who don't need a keyboard and touchpad at all times.

But foldable PCs are very new and have their faults, from durability and compatibility concerns to the crease that can visibly run down the display's middle. Lenovo's Yoga Book 9i announced today at CES in Las Vegas aims to boost pixel count in a way that feels both more and less obvious: replacing the keyboard and touchpad with another laptop-size screen.
