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.

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.
