When I saw the pictures of the Yoga Book 9i, I was skeptical. Many of the foldable and dual-screens I have tried have serious limitations. This is the first dual-screen laptop I have tried that I could actually buy. Many of the obvious concerns that shoppers might have with such a device have been addressed by Lenovo.

There is no visible touchpad on the yoga book i9. The device, which is a laptop-sized spiritual successor to Microsoft's Surface Neo, has two screens stacked on top of each other with a hinge in the middle. Will one navigate this? As I watched the keynote, I pondered.

There are a lot of ways and they all work. You can start touching the screen. The stylus can be used on the back of the device. You can use the virtual touchpad in the software settings. The buttons on the touchpad feel similar to real buttons. You can change the size of this device. It can be moved around. It's your oyster. I think you would get used to it once you get used to it.

The device can be folded at 90 degrees and used like a laptop. This is a feature of single-screen foldable devices as well, but the deal with those is that it usually makes the screen you're working with much smaller, since you're taking a screen you'd previously been using vertically.

The size change when you fold the Yoga Book is not as drastic as it is when you fold it in half. There is a standard-sized 13.3-inch laptop screen with the same aspect ratio as it had before. Another issue with foldables is the fact that the bottom half is not particularly cramped.

When you fold the Yoga Book 9i into a shell, you will see a virtual keyboard and touchpad in the places you would expect them to be. While I don't like using onscreen keyboards, this one is the most clicky and comfortable one I've ever used. The physical keyboard can be placed on top of the virtual one if you want.

The solution to the missing touchpad seems very workable. There are a number of front-mounted keyboards and teensy, crappy touchpads in the space. In previous reviews, I suggested that the trackpads on the dual-screen models were so bad that they should be replaced with something else. I respect the fact thatLenovo has taken that leap.

The Yoga Book doesn't use a special version of Windows 11 but with all the different gestures, it feels like it could be. Four seconds is all it takes to move your windows and applications.

The movie is my favorite. It flies to the other screen if you press and hold on any app or browser tab. The snap layout feature on the Yoga Book will be more useful to many people in the form factor than it will be on a standard Windows laptop.

You can fill both screens with a five finger tap on your tab or window. It's fun to use, but having a giant hinge in the middle of your waterfall makes it look a little dull. If you are using a laptop in clamshell mode, tugging the keyboard down with eight fingers pulls up a little control panel with quick access to weather forecasts, cpu usage and performance statistics, Outlook, and other applications. If you have a mouse plugged in, this is more of a quick reference than something you would want to leave open.

There are a lot of cool things built in this place. The time slot was limited and the representatives were eager to show more tricks. Purchasing this would require some exploration at the beginning, as I don't know every possible position in which you could use this device.

There are a lot of questions about horizontal mode and whether you can use the two screens side by side. Yes, you can, but it is a little strange. The result looks a bit more like a storybook than a work setup when the screens are placed this way. It's something you can do, but it might take some getting used to.

A lot of people asked if the yoga book wobbles. Yes, the answer is The top screen of the laptop is a little wobbly if you tap the screen. I think I would like to do most of my navigation on the non-wobbly bottom screen, which would be closer to me.

Can you make a video on it? The 13th-gen Intel Core i7 U-series chip is not terrible. If you were out and about, you could probably complete a project on it since it is designed for thin and light devices.

It is true that the success of this device will be dependent on the quality of the software thatLenovo creates. The ThinkPad X1 Fold was a bit glitchy to use. My test time was limited, but the yoga book feels better. There have been reports of the device blue-screening during other people's testing, but I didn't experience that myself. When I get my hands on the final unit, I will have many more observations.

Someone may have figured out the right way to do a dual-screen device. This is a great idea. It combines the funVersatility of dual-screens without many drawbacks that I can see. Even though you need to be okay with a hinge in the middle of your workspace, it's just the starting price.
