Funny you should say that because Lenovo made a laptop with an e-ink screen (as graciously linked by someone else in this thread) about a year ago. But it never came to my market, and I suspect this rollable one won’t either. I don’t think they’re serious about selling any of these, it’s just marketing gimmicks.
Because they work three jobs to get food on their table and have to remortgage their house to pay for an ambulance. Privacy is a first-world problem and the US is a third-world country.
