Two Apple patents for the iPad have surfaced in China and it shows some interesting possibilities for the iPad. The first shows that Apple considered a second dock connector on the left side of the iPad in addition to the existing bottom connector, allowing the iPad to be docked in landscape mode and also keep a peripheral such as the Camera Connection Kit attached while the tablet is docked.
The other patent shows that the corner of the iPad could be used to integrate a smart bezel, possibly indicating a touch-sensitive button hidden somewhere there. Of course, it’s hard to imagine Apple introducing another button into the iPad, since iOS generally seems to favor a single home button at the moment, not including the volume and power buttons. Still, the possibility of such a featureis cool.
