Dent Prevention
I put a Speck clear case on mt MacBook Pro, and then I accidentally dropped it off of the famed CalTech steps, and the case protected the laptop 100%, as there were no dents, scratches, or other damage. I then decided to got and 'test' it some more with a dummy computer inside the case and the dummy did not sustain any scratches even though I let it slip down the escalator. I decided to buy another case after that, and I gave the old 'test' case to my friend and put the new one on mine. Definetely buy the speck line of case products!
And the bodyshop idea wouldn't work, but I put some of that metal-softening paste on my friend's PowerBook, and the denht went away after the thing had been smoothed out a few times. However, since the Power Book is made of Titanium and the MBPis made of a softer aluminum, the paste might be a little too strong for the material. Might as well take your chamces, and if it gets screwed up, then cut out the piece of squishy metal and put some aluminum foil over it, and pretend that it was never there...
