Many of today's cell phones and other portable communications devices offer fairly similar capabilities and performance. Still, there are differences among them, and some brands and models may be more suitable to some consumers' needs than they are to others.

Cell phones, which in the past only provided phone and text messaging services, now offer many other features, such as a camera and Internet connectivity. These features are also available on smartphones, which can also be used to check e-mail and to view documents. Some also have Flash capability for transmission of video. A personal digital assistant (PDA), which is really a tiny computer, offers all of these features, as well as word processing, spreadsheet, and other functions. Satellite mobile phones are more expensive than conventional cell phones, but can be used all over the world, including areas where there might not be cell phone service.

When considering a cell phone, search the Internet for websites that compare and contrast the cell phone features and include a list of the strong and weak points of each.

Here are a few tips to consider when shopping for a cell phone:

• Look for a device that offers a long battery life, good sound quality, an easy-to-use and quickly responsive keyboard, and includes a clearly written instruction manual. Consider a cell phone with features that are intuitive to use, so that you can easily learn how to use them. Look for Flash support, music capabilities, Wi-Fi, and other features that are important to you.
• Avoid devices that have a reputation for short battery life, dropped calls, and that have a hard-to-use keyboard.
• Make sure the device is sturdily built and won't break easily if dropped.
