Rather than hitting asmallbutton to answer or initiate a call--as you would with a Bluetooth headset--the Cord Free is ready whenever you pick it up from its base.
If the iPad isn't nearby or isn't connected via Bluetooth, up to 100 pages of writing can be stored on the sensor by pressing asmallbutton on the sensor.
The Instant Dictionary is even more exciting: toggling it in the ASUS Quick Setting panel will bring up asmall round button that snaps to either the left or right side of the screen.
