Lenovo Yoga Book 9i review:

Every now and then, a device comes along and challenges you to consider the viability of an entirely new product category. That’s precisely what Lenovo is doing with the Yoga Book 9i. By replacing the traditional physical keyboard with a second display, the company is rethinking what a laptop can do. In tight confines, you can rely on a virtual keyboard or an included magnetic alternative. But when space isn’t a concern, you can prop the whole system up on its custom folding cover to create an engaging dual-screen workspace. It’s like a miniature all-in-one PC that’s incredibly easy to carry around. And while its software still needs work and it costs twice as much as a standard clamshell, the Yoga Book 9i is proof that it’s worth exploring this new branch of the laptop’s evolutionary tree.
