Multifunction Versus Individual Mobile Devices
A year or more ago, each mobile device you owned performed just one function: Your cell phone made calls, your PDA maintained your schedule, and your MP3 player played music. Now manufacturers are merging many different functions into one device.

How do these multifunction devices compare with their single-function counterparts? It depends on which products you're comparing--but you should keep a few tips in mind as you shop for multifunction devices.

First, check the price of your multifunction device against the cost of separate devices that perform the same features. You shouldn't have to pay a premium for a multifunction device. In fact, because of shared functionality of buttons and the reduced cost of materials, you should pay less for a multifunction device than you would for separate devices.
