Remember that they are NOT doing us a favor by giving us iPads. They are saving money. I don't know the money numbers, but OJI back injuries are very expensive. I know this first hand from a herniated L4-5 disk.
The company also said the weight savings alone is 326,000 gallons of fuel per year. That is $1.4 million per year in savings TO THE COMPANY. Add that to the workers comp costs and loss of flying by injured pilots. Since they are saving money, we can get a raise.
