> both Apples and Googles ecosystem are so tightly coupled with the owner of the device, it's hard to use them in an shared environment I don't know about Google's devices but Apple's Configurator allows businesses to manage devices that are shared between multiple users. The iPad can be put into "kiosk mode" in which it boots to a single application. In this mode it's not possible for the user to exit the application or run any other application. I work on a point-of-sale iPad application for agents in stores and it's working out very well for our customers.
