As our cell phones get smarter, smaller and faster, and enable users to connect at high speeds to the Internet, an obvious question arises: is the mobile handset into the next computer? In one sense, it already has.

Today’s most complicated mobile phones have the processing power of a mid-1990s PC while using 100 times less electricity. And more and more of today’s mobile phones have computer-like features, allowing their owners to send e-mails, browse（浏览）the Web and even take photos? 84 million mobile phones with digital cameras were shipped last year. We ask the question whether mobile phones will ever overshadow or replace the PC, and the issue suddenly becomes questionable. PC supporters say mobile phones are too small and connect too slowly to the Internet to become effective at tasks now performed on the large screens and keyboards of today’s computer. Fans of the mobile phones respond: just wait. Coming techniques will solve the limitation of the mobile phone. “One day, two or three billion people will have cell phones, and they are not going to have PCs,” says one inventor of the smart phone and the chief technology officer of an important smart phone company. “The mobile phone will become their digital life.”

The inventor’s a newest product, the shiny, slim pocket-size cell phone, has a tiny keyboard, a built-in digital camera and narrow openings for added memory. The smart phone market makes up only five percent of overall mobile phone sales today, but the figure has been doubling each year. In the United States, it’s the business crowd that’s primarily buying these handsets. “What makes the smart phone so much better than the computer is that it’s always with you, always up and always ready,” says one of them, who works in an 80-member law firm, which recently started giving its lawyers smart phones instead of laptops.
