单选题 Many people in today's business world are required to be wired and digitally equipped at all times, including cell phones, PDAs (personal digital assistants), and digital cameras, on a daily basis. A simplified system consisting of fewer of these stand-alone products would strongly benefit many people in all industries.
The solution may present itself as digital convergence, which refers to the combination of two or more products simplified into a single product. Many of today's cell phones also allow the user to take pictures, surf the net, and send/receive text messages. There are increasingly newer PDAs combined with cell phones, with highly functional computing capabilities that work seamlessly like desktop computers. It is highly probable that one day soon there will be an "omnipotent" product that can do all these things.
Presently, there are some products that can perform a large number of these functions, but are accessible to those who can afford to pay a high price. However, sometime in the near future, a super PDA that can serve all our required functions and is available at a price that is affordable for the average person may be a reality.
