This week the website Patently Apple has uncovered 2 pending patents put forward by Apple that relate to the iPad.
The first is a thinner design that will make the device easier to hold, but the second is more intriguing.
They have called it a 'smart bezel'. It appears to be a new additional input device/button in the bottom left hand corner of the device.
At this time it is not clear though whether it is a traditional push button or a touch device.
