There's another thread about this here >
https://forums.macrumors.com/threads/203455/ where I posted a photo of where I was cut.
I was really surprised no one made more comments in that thread?
I wish everyone who is concerned about this would email Apple, imo it's a design flaw and so easily corrected I can't believe they over looked it.
If you search here or in google there is a LOT of people who are concerned about it, have chafed their wrists, have to wear long sleeves, or used electrical tape to soften the edge or use an external keyboard.
I called our Business Rep at Apple about it, the reply I got was "we've never heard about that before" ... and that's about it, I didn't pursue it further, I really love my Mac's, the sharp edge is about the only thing I don't like and it's my fault in a way how I sliced my wrist because I got up quickly and where my arm was resting on the edge I 'pushed away and at the same time slid my wrist along the edge ... a few minutes later it was bleeding, I was pissed but I'm not the complain/law suit type of person.
But for all the law suits that fly around nowadays I'm surprised there isn't one over this, or at least a petition..... I dunno ....
