Highly portable, powerful computers with wireless connections will radically change the way people think about and use computing. No longer will users limit their computations to a single machine; rather, they will use the machines that best suit their current needs. A user's environment, which we call the computing persona, cannot continue to be redefined on each machine. Rather, as people move between systems, their environment should follow. The notion of computing persona provides new insight into resource management in a distributed and dynamic world. Resource constraints will vary widely and for-fee services will change optimization strategies. Many of the technologies needed to realize personae are current research topics, and the persona concept will focus that work and make it more valuable.>
