LG GD900 Crystal : LG-GD900 Crystal's slide-down Crystal Touchpad first appears to just be an alphanumeric keypad, but it actually doubles as a touchpad for controlling the phone. It can be used like the trackpad on a laptop computer but also recognises handwriting, responds to multi-touch commands and enables a new way of navigation called Gesture Command.

To launch a feature on the LG-GD900 Crystal, press the phone's multitasking button and draw one of 12 easy symbols on the keypad. Users can assign these symbols to any of the phone's nine multitasking-enabled features.
