I'm stayin NYC for the week, on 33rd, right behind B&H. One day, we were walking by when UPS was picking up shipments. The B&H employee scanned each box, and set it down in the back of the truck. The UPS driver then scanned each package, picked each one up, and threw it as far forward in the truck as it would go. This wasn't sliding, this was a toss at least 4 feet in the air for every package. I watch for about 15 scans, and all of them were thrown forward in the truck, and I could hear them tumble to a stop.
I trust B&H packing (I've bought a lot there), but I know that electronics and complex mechanical systems only have a finite number of jarring motions before they start to malfunction. I hate to think that every UPS handler is going to add to that big hit count as the packages make their way to my home.
