I've been using Macs for decades and never had these issues personally. It seems like some people do literally rest their hands / arms on desk / notebook body while typing.

The "sharp edge syndrome" here to me seems to be a good thing then as it acts as a reminder for proper ergonomics / posture.

First Google AI search result on the topic:

"Never rest your wrists on your MacBook while typing. Instead, let your palms rest gently on the laptop body only when you pause. Hover your hands as you type. This prevents you from bending your wrists and protects the nerves in your carpal tunnel."

That also pretty much exactly mirrors the way we learned typing / posture at school in Austria.

> Hover your hands as you type.

I've been using computer keyboards for 30 years and have never done that.

Still no wrist problems.

I don't typically type on laptop keyboards though, and I use a very firm wrist pad, and sit at a height that makes my wrists nearly perfectly straight.

I've always wondered if this was the secret motivation behind it. I hated this bit of design when I switched from a smooth edged Thinkpad ~15 years ago. But I changed my typing posture for the better and it became a non-issue.

I get the point there and it does make sense, however I think there are certain limits to where it applies. I use it on the go a lot, crammed in small seats in the train for example. In those cases, it's just not always possible to have proper ergonomics and IMO this should be kept in mind when designing a laptop.

Agreed. The sharp edges are like a Victorian teacher whipping you for slouching

They could have put sensors on the body and made it alert you in MacOS, but you know, it is what it is
