Ritsa- iPhone applications

If anyone has an iPhone, or doesn't, I'm sure you have seen all of the applications that are available for use on the phone. There are millions. Some examples include:

• application to find where your car is parked (in case you totally lose it in the mall parking lot)
• GoodFood- best places to find eats in your neighborhood
• prescription drug search- my friend is a nurse and she has an application on her iPhone that lets her describe the pill (color, shape, size) and figure out what it is
• AreYouSafe DC- lets you know how safe you are at any given time based on your current location within the city.
• SpeedoCheck- turn your iPhone into your own handheld speedometer. like reallllly?
• BudgetCare- control your personal expenses

I guess you get my point. You can do absolutely anything from your iPhone. But unless you really want to know how fast you walk, doesn't your car have a speedometer? duh.
