PDAs

Personal Digital Assistants are handheld computers, but have become much more versatile over the years.
PDAs are also known as pocket computers or palmtop computers.
PDAs have many uses: calculation, use as a clock and calendar, accessing the Internet, sending and receiving E-mails, video recording, typewriting and word processing, use as an address book, making and writing on spreadsheets, scanning bar codes, use as a radio or stereo, playing computer games, recording survey responses, and Global Positioning System (GPS).
Newer PDAs also have both color screens and audio capabilities, enabling them to be used as mobile phones (smartphones), web browsers, or portable media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi, or Wireless Wide-Area Networks (WWANs).
Many PDAs employ touch screen technology.

You’ve no doubt started to hear a lot about bluetooth and for good reason. Thanks to its technology, users of bluetooth technology can enjoy low bandwidth benefits through their wireless connections. With its short-range, low power technology, users can easily network without wires. By being able to send and receive data at up to 720kbs, bluetooth customers can use radio waves to communicate with each other, or their Bluetooth enabled devices.

Imagine a world without wires.
