If you are acrostically challenged in this day of initials, let's start off with a few basic definitions necessary if you are looking to upgrade from Post-it notes and Daytimers.
PDA — personal digital assistant
PIM — personal information manager
WiFi — wireless fidelity
GPS — global positioning system
A PDA is a small, hand-held flat box about the size of a small notepad with a monitor to help you keep track of
your appointments, calendar dates
addresses and contact information
agenda items, to do lists
notes or memos to yourself
in effect becoming your personal information manager (PIM). Add on cell phone capabilities, a GPS and some wireless connectivity and you have a full service office right in your hand.
With over 25 manufacturers, each with its own scale from simple to high tech, the purchase of a PDA can be overwhelming. It helps to start with your basic needs, plus those features that would make life easier, and then the added extras that are just "way cool".
