Foldable phones are a thing. It only makes sense that PCs follow suit. The Lenovo ThinkPad X1 Foldable PC blurs the lines between tablet and laptop not by hiding a keyboard somewhere, but by letting the screen itself bend to a clamshell format. Powered by an Intel processor running a special version of Windows, it has a 13.3" OLED 2K display from LG that can fold in half, reducing its width by 50%. As you might expect, it's just a preview for now, but the company promises full details and availability in 2020.
