It may not boast two screens, but the Lenovo ThinkPad X1 Fold Foldable PC does something else. This single-screen device folds up to the point where it looks like a book or journal. So when you’re not using it, its screen stays protected in your bag. And this folding ThinkPad isn’t just a combination of two screens. When fully open, this foldable ThinkPad has a maximum viewing area of 13.3 inches—which is all OLED, by the way. When you’d prefer to use two separate screens, like a book or laptop, each one is 9.6 inches. With an Intel Core processor inside, the X1 Fold also uses the Windows 10X operating system. Pair this with the fact that it’s built with 5G connectivity, and this is the computer that ensures you’re always connected.
