It's a laptop, but it can be anything—the Lenovo Yoga Book 9i has the conventional shape of a clamshell notebook, except that there's a second touchscreen where you'd expect the keyboard an trackpad to be. You get a folio-type silicone keyboard with physical keys that provide tactile feedback, or you can pull up an on-screen keyboard on either screen and type with haptic feedback. As a Yoga product, the hinge turns 360°, and at 180° it can become a dual-screen setup. The possibilities are endless.

Under the hood is an Intel Core i7 U-series "Raptor Lake-U" 15 W 2P+8E SoC with 16 GB LPDDR5X memory; NVMe Gen 4 SSD, integrated Iris Xe graphics, and an 80 WHr battery. Each of the two 13.3-inch touchscreens has a 16:10 aspect-ratio and 1920 x 1200 resolution. Comms include Wi-Fi 6E, and Bluetooth 5.2 (a 5G modem would be incredible).



Elsewhere in the Lenovo booth we see the ThinkBook Plus Twist, which is essentially the same device as the Yoga Book 9i, down to its 13.3-inch touchscreen, but there's only one of them—the other half has a conventional keyboard and trackpad, and a smaller 56 Wh battery. The Legion Pro 7i is the company's high-end gaming notebook, featuring a Core i9 6P+16E "Raptor Lake" processor, an NVIDIA GeForce RTX 4070 Laptop GPU, dual-channel DDR5-5600 32 GB memory, 1 TB NVMe Gen 4 storage, and an incredible 16-inch 2560 x 1600 (16:10) display.

How does it stand when in dual screen mode? It's an interesting concept, though a trackpad would certainly be nice. The other odd thing I noticed is that Windows 11 doesn't seem to know what to do with it. In vertical mode, the screen hasn't rotated, and in horizontal mode, you get dual task bars, where just one at the bottom would probably be sufficient?

I like the ThinkBook Plus Twist with its center-hinged design, haven't seen any convertible using it in quite a long time. The 12 inch secondary E-Ink panel (which, by the way, is left out in the OP) could have some use as well.
I do wish it have LCD 1920x1200 option though as Lenovo's PR for it only mentions OLED "2.8K" in the spec. Burn-in is the dealbreaker for OLED on PCs and anything beyond 1920x1200 on 13 inch is just overkill.

If it's anything like my Yoga, It'd have a button to lock rotation. Also the taskbar thing can be changed in settings on Windows 11...

Looks very nice, but price will rule it out for me at over $3K in Australia for entry level. Refuse to pay stupid money for a laptop that can never be upgraded. The Tab Book with 12.3" e-ink secondary display looks like it might be more affordable.
