What is a Bluetooth Keyboard?
In most definitions, a Bluetooth keyboard is one that uses the Bluetooth wireless protocol to connect the keyboard to a mobile device, such as a cell phone or a Personal Digital Assistant (PDA). Essentially, any standard QWERTY keyboard that makes use of Bluetooth could be considered a Bluetooth keyboard, but the most common definitions limit a Bluetooth keyboard to one that connects to a small, mobile device that doesn’t contain its own keyboard. The cordless nature of the Bluetooth keyboard, which typically runs on AA or AAA batteries, makes it quite handy and usable nearly anywhere. In most cases, the Bluetooth keyboard, which may include a touch pad too, is actually one that can fold up when it isn’t in use. This makes it especially easy to carry along with a mobile device. Keep in mind that most Bluetooth keyboards are not as large as the standard size you’ll see with a computer keyboard or even with a laptop computer. The small size of the keys can make them uncomfortable to use
