Lenovo’s rollable display laptop from CES will cost at least $3,500

Almost two years ago, I got to spend a few minutes on what was then a concept device, Lenovo's laptop with a rollable OLED display that extended from almost 13 inches to 15 inches with a push of a button. The device was a work in progress, and I had no idea whether Lenovo would turn it into an actual product.

But Lenovo seems to have covered a lot of ground in the past two years. The company made a few changes to the rollable display laptop and decided to launch the product commercially.
