I have a Unibody Macbook Pro, and usually I take it places in my briefcase, which is fairly large. However sometimes it would be nicer to have something smaller to put it in. If I were to buy a Incase sleeve for my MBP, (http://goincase.com/products/detail/15-neoprene-sleeve-cl57256/2) and it were dropped 3-5', would that put a dent into it or cause serious damage? Lets say it were being dropped on tile.
