Aside from a rollable smartphone concept (through Motorola), Lenovo is also exploring bringing the technology to its laptops. The rollable laptop concept looks like it has your typical landscape display, but then it rolls up to a square shape. This form factor should make it easier to view documents or look at things like vertical videos. As with foldable smartphones, it opens up the possibility of packing in a larger display into a smaller or at least more compact form factor. We don't know if this concept will ever see the light of day, but we'd love to see Lenovo take a shot at bringing this to market.
