When the notebook is placed on top of the docking station, its unique shape provides a more comfortable typing position and allows for better cooling of the notebook. Another factor unique to Targus’ Docking Station is the "Always On" capability. A button on the back of the device allows two of the four USB ports to always have power, whether the notebook is powered down or in sleep mode. This allows USB devices plugged into the docking station to continually have power or to recharge. A great use for the "Always On" feature is to continuously charge devices such as mice, phones or PDAs. Targus’ four USB ports are also adapter friendly, meaning they are spaced twice as far apart as typical to allow any size of adapter to be plugged into the port.
