As small as a credit card, the iPhone Bluetooth keyboard also functions as a mouse for your mobile phone as well as tablet.
Functioning with the help of two AA batteries, the iPhone Bluetooth keyboard is as light as 70 grams, making it easy to carry around with you on the run. While the keypad is only compatible with Apple products from iOS 4 and on at this moment, it seems quite efficient, including other functions such as hot keys for the cell phone. Embedded to the top right corner of the pad is a touch-sensitive mouse that's directed by light simple strokes. The price for the compact Bluetooth keyboard is only $40, which is almost the same as wireless computer mice these days.
