That palm rest corner is razor sharp even compared to earlier MBP designs, and it finally made me get a silicone palm/lower arm rest.
It is probably the best purchase I’ve made the last few years, I’m so happy with it every single day and it just makes working with laptops such a joy.
Make sure to get an extra wide one, mine is something like 70cm wide and I can keep my mouse and laptop a good distance apart and have the silicone support under both my arms.
