Personal Digital Assistant -or- Public Display of Affection
A handheld portable computer, it is a small device that contains a digital calendar, an address book, a memo pad, a set of accessories, and other features. There are a variety of software programs designed to work specifically with PDAs for fun and business, and several models now offer Internet access.
PDAs are morphing with other technologies and are commonly referred to as a handhelds. They can receive input through a keyboard, a stylus, and best of all, a built-in touch-screen display. Gadgets such as the Palm Pilot, Handspring, and the old Apple Newton are considered PDAs. Apple's former CEO John Sculley is credited with using this term for the first time in 1992. Since then, the Blackberry and iPhone have emerged as modern PDAs.
