Although I not only work with high tech but also invent it, I am
somewhat of a luddite having never sent a text message or even looked
at a "tweet" and iphones were far off my personal radar but at
Thanksgiving, my sister showed me her iphone and some apps and I
immediately went into "inventor" mode seeing the possibilities.
Why not an app that helps id fish and keeps up withe the constantly
changing fishin regulations?
Why not an app that turns the GPS equipped phone into a chart plotter
( just found this one exists, it is called "inavx")?

Other possibilities:
For my diabetic daughter: *An app to calculate carbs of a meal based
on what you eat.
An app to quickly calculate your cars mpg when you fill up.

A "stethoscope" app using the phone held to your chest.
A birdsong app identifying birds based on the calls it hears from
Fourier Analysis.

I really like my iPhone. It's much better than the Treo it replaced.

The killer app for me is the Weather Channel. It has a weather radar
function that not only gives you the current image, but will also put
the last half-hour or so in a loop mode, allowing your to see where
the weather is coming from and is headed to. I keep it by my side
when out on the boat on days with possible thunderstorms. That's when
it's nice to have a pontoon that'll run 40mph.
