Maybe those guys use them because they can or that they haven't caught up with the trend. In my country, everyone uses a smartphone (practically speaking). Delivery, repair, inspection people, all use their smartphones to take photos and upload to destination via an app. Apart from being convenient, this has a side effect that the organization can push device cost onto individual contractors and lay people. I'm fully certain western countries will catch up with this trend just to save a buck.
