One mobile phone which has raised the bar for the others and represents the phenomenon of life revolving around the device is the Apple iPhone. Apple also provides the same device sans phone capabilities as the iPod Touch. However, the iPod Touch doesn't have the cost subsidization from the mobile phone provider so it actually costs about twice as much. I suppose if you already have a mobile phone with another provider and you are locked into the contract, maybe it makes sense. But, for the extra money you spend on the iPod Touch you could just pay the early termination fee on your existing mobile phone contract and get an iPhone. But, I digress.
Users have to remember a variety of passwords and account information details. Often, faced with the difficulty of recalling them all, users resort to writing them down or keeping them in some sort of text file that could compromise everything if it fell into the wrong hands. Since the mobile phone, in this case the iPhone, is generally on hand it makes perfect sense to store this kind of information on it. No matter where you are, you probably have your iPhone handy and can pull up the information in a few seconds.
Of course, criminals also realize the value of these devices and the information they contain. Mobile phones like the iPhone are small by design and are easily lost or stolen- along with all of the information they contain.
