New apps for hand-held devices

I have to say I have seen more and more iPhones these days and it's not surprising why. Have you seen all of the new apps being created?

How about creating an app that lets you instantly know how to handle yourself in certain situations.

For example:
Say you're on public transportation and you feel someone is being impolite- quick whip out your hand-held device and get three options for how to react.

Or what about one that combines map navigation with avoiding a speeding ticket? The device will detect where there are highway patrol cars and provide you with an alternative route to your destination to avoid speed traps (not that I'm speaking from experience :)

And what about people with low self-esteem? How about an app that at various times of the day will send them positive affirmations --- like Stuart Smalley from SNL
