单选题 2. A Sophisticated Device for Sophisticated Communication
As wireless communication has become more sophisticated, consumers have more and more choices of ways to communicate and organize their lives at the same time. So, what kind of device do most people want to carry in the future? A Personal Digiml Assistant(PDA) that talks or a cell phone that can handle data?
There's evidence that smart cell phones are winning the hearts of consumers. There are certainly lots more cell phones in people's hands. Sales of cell phones still outnumber those of PDAs. The simple reason for this is that users find wireless phones convenient and easy. There's no special knowledge required to use them; everybody already knows how to make phone calls. To maintain their advantage, however cell—phone manufacturers should continue to design their phones primarily for voice communications. Other applications need to complement voice features, not compromise them.
There are a number of design criteria that cell phone manufacturers must take into consideration as they are essential to successful market appeal. Cell phone designers need to keep in mind that people buy these devices first to communicate, not to compute, so they need to remain easy to use. Therefore, most importantly, new combination devices need to look like phones. The familiar look of cell phones also makes it easier for technophobes, who fear new gadgets, to accept devices with more complex capabilities. The average phone user prefers a simple keypad, not a stylus for writing on a screen. Small size is also valued. After all, convenience is what has made cell phones so popular in the first place.
Given these criteria, however, the appeal of technology is to offer the customer innovation— something new to capture their imagination. So, what are manufacturers adding to cell phones? Anything that requires a lot of typing or a large screen won't work. Word processing, spreadsheets, or even most web surfing isn't practical. Successful smart-phone applications need only to add to the convenience of phones. Making it even easier for the consumer to stay in touch and be productive is the priority. As such, some useful applications could be personal information management programs, such as an address book, calendar, or a" to-do" list, which automatically communicate with the user's home—or office—based PC. Also, phones can be programmed for access to specific Internet data and functions that the user chooses. They can offer phone directory searches and driving directions. More features might include short messaging services, e-mail, and fax.
