Lenovo is showing off a laptop with a glasses-free 3D display at Mobile World Congress 2025, and it feels a lot like a supersized Nintendo 3DS.

Lenovo has another funky experiment it’s announcing at Mobile World Congress: the ThinkBook “codename Flip” AI PC Concept. It’s a productivity / business laptop with a flexible display, allowing it to be used as a traditional 13.1-inch clamshell, a folded-up 12.9-inch tablet, or a laptop with an extra-tall 18.1-inch vertical screen.

Fitting an 18-inch display into a 13-inch laptop body the way Lenovo has done for its ThinkBook Flip is clever, as it's a great way to get more screen real estate in a compact design — bar getting a portable monitor.
