Actually, come to think of it, this story about a guy getting first aid advice from an iPhone app reminded me of a brand of first aid kit that came out a number of years back. Smaller sub-kits for different injuries (burns, cuts, fractures, etc.) were color coded. But the interesting part was that it comes with this handheld electronic device that verbally asks the person questions to figure out the problem, and then suggests how to deal with the problem.

Some may dismiss the need for such a device, saying just take a good first aid course, but probably most of us have experienced our minds going blank in a stressful situation, so I can see the benefit of anything that helps coach a person through such a situation. Anyway, just a random thought.
