This is really obvious 'round-tripping' no? Nvidia invests in startups that are going to spend a majority of their funds on GPUs, Nvidia's revenue goes up, Nvidia's stock goes up, Nvidia makes more 'investments' in startups who use that investment to continue the cycle?
I cannot possibly imagine what I'd do with a "rollable" laptop, but I do see one tiny benefit to foldable phones; reduced pocket consumption. Having a smaller device or a device that gets smaller is just two different ways to solve my main beef with modern phablets.
Personally, I wish someone would just make a clamshell smart phone where I open it up to a single screen on one half and a physical keyboard on another, but that's a different discussion.
That all said, I'm curious to hear from the people who want this device. What's drawing you to it? What problem does this type of display on a laptop solve for you? What are your concerns about its robustness or longevity, if any?
I'm not sure about robustness, would have to wait and see tests.
