The table below lists a variety of gadgets and devices that can be replaced with Apple iPhone functions. Many of these functions are integral to the iPhone while others can easily be added with download of a free or low-cost app. Simply put, the iPhone can replace several hundred dollars worth of electronic gadgets – and combine them all into one portable and easy to use device. Another blogger logged twenty-three devices he was able to replace with his iPhone.

Police scanner app for the iPhone lets you listen in on emergency calls from cities around the world.
In some cases, iPhone functions may not be as robust as a stand alone device. The Kindle e-reader app for the iPhone, for instance, is not as good as the Kindle itself. Still, it is a very good e-reader that will suit the needs of many people. Moreover, it is a lot easier to carry around. For me, the Kindle has become the e-reader I use at home while the iPhone is what I use when traveling.

The Payoff: As you can see, the Apple iPhone can pay for itself by replacing useful and necessary devices you might otherwise need to buy. The iPhone is a true modern-day Swiss Army knife. Carry an iPhone with you and you will always have a flashlight, music player, camera, voice recorder, compass, calculator, level, GPS, flash drive, alarm clock, stopwatch, pedometer, e-Reader, and emergency scanner with you as well. I figure my savings to be at least $400.
Loved the iphone, that was until the droid came out and made everything open source
