I dropped my 15" Pbook froma bout 5 feet onto concrete sidewalk. My bag strap snapped and the corner hit. Because of that it has a nice dent on the corner, I had to have the apple store pry the metal away a little so I could get the AC Adapter in, and there's a small crack on the LCD. Screw you sidewalks
Also, last week, I had my pbook in my bag and my bag fell and hit a leg of a computer chair, there is now a small dent on the lid.
I also had a close call last week I took my Sawtooth and my Pbook home. I had my sawtooth on the backseat. and my bag with the keyboard/mouse, adapters, etc etc in it. The bag also had my pbook. I braked REALLY hard and felt a hard push on the back of my seat. Oh crap. The Sawtooth hit the back of the seat, knocked over the bag with my pbook in it, that fell on te ground and then the sawtooth landed on top of the bag. Miraculously NOTHING was hurt at all in this incident. My pbook has no new scratches dents or anything and the sawtooth went home and booted like a champ.
