    I'm not thinking of programming on these things. But, for example, having a turn-key app on an iPad that solves one well defined class of problems one wants to solve out in the field.

What that well defined class of problems is I don't have a clue. Maybe as Jed climbs a glacier he can be scanning in the temperature, shape,… and it can be running a simulation to show how much of the ice will be gone by the end of the summer.
