When I was in college, I used a 12" PowerBook as my main laptop. It was an absolutely wonderful little computer, that I still have around. One day, I was rushing down a flight of stairs to get to class when I tripped and sent myself and my bag flying. It was one of the science buildings, and the stairwells had these large pipes mounted to the walls going between the floors. I landed flat on the floor, while my bag continued on, smashing side first into one of the large pipes, putting a beefcake dent in the side of the PowerBook, bending in the SuperDrive and lid. After an evening of swearing, screwdrivers, and small hammers, the little PowerBook was back to 100% functionality and looked fairly decent once more. It went on to serve me well for several more years, and in fact continues to function just fine.
