PDA (personal digital assistant)
Data-centric handheld computer weighing less than 1 pound that is designed primarily for use with both hands. These devices use an open-market OS supported by third-party applications that can be added into the device by end users. They offer instant on/off capability and synchronization of files with a PC. A PDA may offer WAN support for voice, but these are data-first, voice-second devices.
