Ugh. After over a decade of work, everything was finally adapted to or made for 16:9, now they're going after hipster ratios? Not a deal breaker but a bummer. Interesting that phones are going the other way, so now we can enjoy letterboxes on both platforms and not be able to reach the notification drawer. What was so wrong with 16:9 that we needed another competing standard that's just slightly off...
I welcome the extra vertical space and couldn't care less about watching video content full screen. Do that many people buy these laptops as portable Netflix players?
Until 4k became more popular maybe five years ago, the vast majority of devices were 1920x1080, plus a series of budget 1366x768 devices but that's the same ratio. Upscaling an integer factor to 4k is also convenient and doesn't cause any issues, just makes everything sharper.
It's when you start to mess with the ratio that you need to suddenly account for different people having different things in view. You can't simply scale a hero image (or game scene or so) to 20:9 without everything becoming contorted, you need to start to crop, but then you're hiding information so now you need to add optional parts that don't look out of place when shown and can also be hidden without consequence.
