One of my clients provides maintenance services to retail stores across a four-state area. We gave their carpenters, painters and other workers iPads to replace clipboards for filling out work orders. Job schedules are also sent to the workers on the iPad. Another client is using iPads in their marketing department to complete "mystery shopper" reports as they visit their 400 retail locations.
