Lenovo’s Yoga Book 9i is a dual-screen clamshell touchscreen laptop that brings a unique form factor to the market. The device features two 13.3-inch OLED touchscreens with 16:10 aspect ratios, offering users the ability to work with two equally sized Windows desktops simultaneously. While the concept of two screens may be appealing, the Yoga Book 9i does come with some compromises and limitations that may not replace traditional clamshell laptops just yet.
In terms of design, the Yoga Book 9i looks like a typical 2-in-1 convertible laptop, with a dark blue aluminum chassis and rounded, polished sides. It is about the same thickness as a MacBook Pro and features a lip on the top half for easier opening and a Windows Hello-compatible webcam.
Cracking open the device reveals the unique aspect of the Yoga Book 9i. The two OLED touchscreens light up, providing two separate Windows desktops. The screens are vibrant and color-matched, with a peak brightness of 400 nits.
The device offers different postures for usability. The default clamshell mode, where users try to use it like a standard laptop, is the least ideal. The virtual keyboard on the bottom screen, although large with light haptic feedback, does not provide a great typing experience. However, users can use the included Bluetooth keyboard for a better typing experience. The virtual trackpad on the bottom screen also feels sticky and is not as smooth as an actual hardware trackpad.
One of the most productive postures of the Yoga Book 9i involves using the Bluetooth keyboard, folding stand, and a mouse that come with the device. By propping the device up vertically with the stand, users can see both screens at the same time, effectively turning the 9i into a multi-monitor productivity machine. Windows recognizes it as two separate displays, allowing for practical use cases like browsing the internet while keeping an eye on chat apps or email. Users can also participate in video calls on the top screen while referencing or taking notes on the bottom one.
Another useful feature is the ability to write notes on the bottom screen while referencing the top screen. The device can also be rotated 90 degrees to have two portrait-oriented screens side by side, useful for comparing two documents simultaneously. However, landscape orientation is generally more preferred.
While the dual-screen concept offers unique advantages, there are some downsides. The device is not suitable for lap use and requires setting up a workstation with the included stand, keyboard, and mouse. This may cause friction for users who are used to the convenience of traditional laptops. Additionally, the device comes with some software quirks, such as the mouse cursor getting trapped on the bottom screen and the inability to use the trackpad for Windows security prompts.
Included with the Yoga Book 9i is a stylus that can be stored in a fabric loop on the folding stand. The stylus works on either screen and can be useful for taking handwritten notes or using the space above the keyboard as a scratchpad for reminders.
Overall, the Lenovo Yoga Book 9i offers a unique dual-screen form factor that has its advantages and limitations. While it may not replace traditional clamshell laptops just yet, the device provides a compelling pitch for users accustomed to working at a desk. The clever software and hardware tricks implemented by Lenovo make the dual-screen experience surprisingly usable. However, the device’s high price, software quirks, and the need for additional accessories may not make it ideal for everyone.
