As a laptop reviewer of over 10 years, it’s tempting to think you’ve seen it all. Laptops with foldable displays or even dual screens have come and gone, as have a half-dozen other gimmicky trends. Then a box arrives at your door that subverts what you thought was possible. That’s the Lenovo ThinkBook Plus Gen 6 Rollable. We first saw it at CES 2025. It’s a laptop that can extend from a 14-inch display up to 16.7 inches, all at the press of a key. It’s the party trick to end all party tricks. And yet, as I lived with this machine, I found it far more practical than I assumed it could be. Roll Out Photograph: Luke Larsen There’s nothing quite like the ThinkBook Plus Gen 6 Rollable. It uses the same curved OLED technology as seen in concept televisions and smartphones but never in a product this commercially viable. (I should note that as of publication time, Lenovo’s retail page says it’s not yet available. We’ve asked Lenovo for a concrete timeline on availability.) It starts as a 14-inch display with a 5:4 aspect ratio, which is already odd. That's as square a laptop display as you’ll find. But then push the dedicated key in the function row and the magic happens. The gears start rotating, the mechanisms crank up, and eight seconds later, your laptop’s display has expanded up to 16.7 inches, which is 50 percent more screen than before. Just watching it transform is fun. Seeing that display unroll out of the hinge feels futuristic. Now, I’ve always been a fan of vertical space on laptops. I tend to prefer 3:2-aspect-ratio devices like the Surface Laptop over 16:10 or 16:9. At its full extension, though, the 16.7-inch screen (measured diagonally) has an 8:9 aspect ratio, making it considerably taller than it is wide. It looks both awesome and ridiculous simultaneously. Nothing will catch the attention of every other person in a coffee shop like rolling up with one of these babies. The use case is not that you'll be switching between these two sizes while in the middle of your workflow but instead that it's a portability benefit. While it's in your bag, it's just a 14-inch laptop, but when it's out on your table, it can grow into a much larger screen.
