> laptop keyboard leaves marks on screen.

I don't think this has been a thing in years.

Sharp edges on wrists is true.

My 2023 MBP's keyboard leaves marks on the screen while closed.

It definitely is a thing on my M2. Unsure if it is something that was fixed in the later models.

My wrists, conversely, are fine, but I suppose I rarely use it in a 'classic' desk position that would cause that.
