not just pilots, I see them in use by nearly every service person who comes to the house and even at work. they are just the right size for easy reading, the lack of keyboard removes a major breaking point if not cleanliness issues. throw in they just give a modern and sleek vibe to any organization employing them versus pen and paper.
plus they make it easy for customers to sign for services which in turn makes it easier for businesses to know that the work was done. toss in CC readers that attach easily and you have a simple POS device
if anything the amount of waste that would come back into our lives without them would be staggering
