It used to be that every division officer worth his salt carried a small, green, U.S. government-issue "wheelbook" notepad. Handy for keeping track of personnel notes, phone numbers, and the like, these notebooks were pervasive and essential.
Although these notebooks are not completely extinct, you are much more likely today to see someone with a personal digital assistant (PDA). In fact, PDAs in the military are nearly ubiquitous-from landing signal officers using Palms to score fellow pilots to sailors keeping track of equipment maintenance. The latest generation of these pocket computers are wonders of convergence, coupling personal information managers with cell phones, cameras, and web browsers. With a proliferation of new PDA technology on the market, it often is difficult to make sense of all the choices and tradeoffs.
