a week or two after i got my mbp, i had it in a sleeve, designed for it of course, an STM one... i had that inside a shoulder bag thingo... like a messenger bag (soft).
I was walking along, one of the clips on the strap to this shoulder bag just decided to come undone, my whole messenger bag dropped to the floor (asphalt road surface)... corner first.
when i got to my car I inspected the damage and fired it up... front left corner of MBP dented in only just slightly, boots okay, still works 100%..
it pissed me off for AGES.. i was so mad. but now it's cool, no one has ever noticed it, it's very subtle... kinda add's some character now! haha.. at least it's personally marked now
