I just picked up a Pelican 1470 case for my Blackbook. Other retailers, some except for Pelican themselves, have advertised the case as shock proof. I'm not going to toss my macbook (inside the case) off the top of a building, but I do wonder how well would it hold up. I saw a video where they put a glass vase inside a Pelican case, then tossed it off a silo, but the same could be done with wrapping it in a couple pillows. I am not worried about the actual physical damage to the macbook casing, but rather the internals that may potentially get damaged. I already had my hard drive replaced after dropping my macbook flat on tile. Just wondering how much can my macbook with stand.
