I understand that we all have different sized hands/wrists/arms and we place them differently on our laptops, but I seriously can't stand those marks on my wrists that look like I'm cutting myself. Not only that, it kind of hurts after awhile. Call me a pansy or whatever for complaining, but I just received my macbook pro and within the first hour of using it, I cut my knee on the sharp edge and was bleeding! Whether you think I'm a clutz or not, if I just lightly sit on my bed (where my laptop is) and my knee comes in contact with the edge, I shouldn't be bleeding!
