- iPad POS are popular in smaller coffee shops and similar outlets
- iPad-based document viewing solutions are used by pilots to replace large bags with manuals for planes that they used to lug around
- iPads are used for meeting room management solutions, information displays for customers and similar purposes where one single application is to be run basically 24/7 on a device with low power and space requirements, but where certain aesthetic requirements to the app as well as the hardware have to be satisfied
Granted, iPads don't hold this space exclusively. But so don't iPhones or Macs hold their respective application spaces exclusively, even though they significantly catalyzed their genesis.
