Depending on how I'm using the computer, I may definitely have deep marks after working laying down, but if I sit in a wood chair for a while it's the same thing- and my forearm is much tougher than behind my knee.

I suppose I would prefer it nice and rounded and soft on my wrist - but I don't feel like it's quite as extreme as this thread would have you believe lol

I use a case on my MacBooks to protect them from damage. These cases are made of softer materials that are easier to chamfer. I make a similar modification when necessary. Sometimes it's worse with the plastic cases because the injection mold seam is that sharp edge.

Love that he took it so far. I filed mine a while back - it’s so much more comfortable to use. When I drop it and a corner get mashed, I file that back flat. It reminds me of kintsugi where it shines from the fine filing.

I filed my work dell laptop too. Very different feel, but it is nice not living in feel of your own stuff.

The sharp and high edges leave a mark in my skin. The older MacBook Air design was lower, so resting your palms wouldn’t give me this

my m1 max macbook pro 14 has small little divots out of the edge on the right side (not on the left) presuambly because of where my wrist sits when using the track pad. It would be nice it there was some radius on it to not cause that.

I salute your can-do spirit and your will to customise your tools to your preferences.

I also think you're an animal and need to be stopped before you do more damage to perfectly well designed machines.

A very even 45 degree cut, like the cut to lift the screen but much shallower would look pretty cool. Maybe 2mm wide

What was wrong with a $20 palm rest/cover? It would also protect it for resale value.
