Lenovo 2-in-1 Series Yoga Book 9i (14″ Intel) 83KJ0000US Review

So, you're looking at the Lenovo Yoga Book 9i. It's not your average laptop. This thing is a dual-screen 2-in-1, which means you get two stunning 14-inch OLED panels stacked on top of each other. It's a wild design that immediately makes you rethink how you use a computer. You can use it as a traditional clamshell, a massive dual-screen workstation, or fold one screen back to use it as a tablet with a keyboard. It's a gadget that genuinely makes you smile when you open it up.

This laptop is built for a very specific person. If you're a creative professional, a multitasking fiend, or someone who just loves cutting-edge tech for media consumption, this is your machine. The dual screens are perfect for having reference material on one screen while you work on the other, or for watching a movie while you browse. It's not for hardcore gamers or people who need maximum raw power for video encoding all day. It's for the person who values a unique, immersive experience over brute force.

What makes it so interesting is how it pulls off this dual-screen trick without feeling like a gimmick. The hinge is solid, the software (Lenovo calls it the Yoga Book Creator Zone) is actually useful for managing windows across both displays, and the included Bluetooth keyboard and folio stand are genuinely good. It feels like a complete, polished package, not a proof-of-concept. At 1.22kg, it's also surprisingly portable for what it is.

Let's talk about what's under the hood. The Intel Core Ultra 7 155H processor is a solid performer, landing in the 79th percentile for CPUs. In practice, this means it breezes through daily tasks, handles dozens of browser tabs, and manages complex office workloads without breaking a sweat. The 1TB NVMe SSD is fast, too, sitting in the 78th percentile. Where you start to see the limits is with the integrated Intel Arc Graphics. Its 59th percentile ranking tells the story: it's fine for light photo editing and driving those beautiful displays, but it's not a gaming rig. Our benchmark for gaming was a low 22.1 out of 100, so you're looking at older titles or esports games on low settings.

The real performance story here isn't just about benchmarks, it's about the screen. That 92nd percentile rating is no joke. Each 14-inch OLED panel is 2.8K, runs at 120Hz, and hits 500 nits of brightness. Colors pop, motion is buttery smooth, and the contrast is infinite. Having two of these screens is an absolute game-changer for productivity and entertainment. Watching a 4K HDR movie on one screen while you have a chat app open on the other is an experience no single-screen laptop can match. The 88Wh battery is decent, but powering two OLEDs does take a toll, so expect a full workday but not much more.

Here's the blunt truth: the Yoga Book 9i is a terrible value if you judge it purely on specs-per-dollar. At roughly $2200, you can get a blisteringly fast gaming laptop or a top-tier MacBook Pro with way more raw power. You are not buying specs here. You are buying an experience. You're paying for the engineering that crammed two premium OLED screens into a 1.22kg chassis, for the unique hinge, and for the sheer cool factor.

Compared to its most direct competitor, the ASUS Zenbook Duo (which also has dual screens), the Yoga Book often commands a premium for its more refined software integration and the included keyboard/folio stand. It's a luxury tech item. If the dual-screen life is non-negotiable for you, the price might be justifiable. If you just want the best performance for your money, look elsewhere immediately.

The most obvious competitor is the ASUS Zenbook Duo. It offers a similar dual-screen concept, often at a slightly lower price. The trade-off is that the ASUS design can feel a bit more utilitarian, and its software for managing the screens isn't quite as polished as Lenovo's. The Yoga Book 9i feels more like a cohesive, premium product.

If you're considering this but also looking at traditional laptops, the Apple MacBook Pro 14-inch is a fascinating contrast. For similar money, the MacBook (especially with an M4 chip) will demolish the Yoga Book in CPU performance, battery life, and likely GPU tasks. But you get one incredible screen, not two. The MacBook is a workhorse; the Yoga Book is an experience. Then there are beasts like the MSI Vector or Gigabyte AORUS gaming laptops. For the same $2200, they offer desktop-class graphics for gaming and rendering, but they're thick, heavy, and have mediocre battery life. They're tools for a specific job, while the Yoga Book is trying to redefine the job itself.

If you're a creative professional, a consultant, or a power user who lives in multiple apps at once and values screen real estate above all else, the Yoga Book 9i is a revelation. It's a legitimate productivity booster and a joy to use for media. The dual-screen workflow, once you get used to it, is hard to give up.

However, I can't recommend it to most people. If you're a student, a gamer, a programmer who needs sustained CPU performance, or just someone who wants the best all-around laptop for their money, look at a MacBook Pro, a high-end Windows ultrabook, or even a 2-in-1 like the Surface Laptop Studio. The Yoga Book 9i is a brilliant, niche device. Buy it because you're captivated by the dual-screen dream, not because you're looking for the best specs sheet.
