I normally wouldn't make it a point to praise/brag about something like this, but it impressed me enough to tell the masses (MacRumors, lol). My backpack has a side zipper that stores my laptop in behind the main compartment. It works great because it's a padded section and leaves the main large compartment for all of my books and paperwork. It works great IF you zip up that compartment! So three weeks ago I was rushing out of the office and forgot to zip it up apparently. I pulled my backpack out of the car and swung it around to throw it on my shoulder. Two seconds later I hear the sound of something heavy bouncing off my concrete driveway. This isn't smooth white paved driveway, mind you. This is worn down blacktop driveway. I turn my head to see my MBP on it's third bounce, with each bounce occurring on a corner as opposed to landing just flat. It dropped a good 4-5 ft as I'm 6'4. Naturally, I figure it's toast. Fully expecting to have to show my bosses the idiot I was and assuming I'd find a shattered LCD when I opened it up. No cracks on the screen and everything still works perfectly. I've given it a few weeks to see if anything would show up and nada. I did a number on the rear corners which effectively demolishes any resale value this thing might have had, but it operates like it never happened. I don't know if it was because of the unibody construction or what, but I wouldn't expect any laptop to survive this. There are many other reasons why I would go with a MBP again, but this just solidifies my stance.
