The author of The Verge carefully studied these devices. Unfortunately it is not yet clear when they will go on sale – Lenovo does not provide such information.
With the laptop screen on, it looks completely normal. Everything changes with a small button located on the right side of the case. You may hear a buzzing sound at this time, the screen will scroll up. The result is an almost square 15.3-inch display with an 8:9 aspect ratio.
Another Lenovo dial-up device shown at MWC is a Motorola smartphone. In its normal state, there is a 5-inch display with an aspect ratio of 15:9. Then, after double-clicking the side button, the screen turns on and the user gets a tall 6.5-inch screen with an aspect ratio of 22:9.
