Patently Apple has found new iPad design patents from China that show an extra 30-pin dock connector port that'll allow for landscape docking and a mysterious feature which may be Apple's "Smart Bezel Feature".
If this new design is real, it makes some sense (at least, more sense than a 7-inch iPad). Having the option to dock the iPad in landscape mode would double the convenience for iPad owners who, well, frequently dock their iPad.
The Smart Bezel Feature is very interesting but we don't know what it'll do. Does it act like a button or is it more of a gesture area? The previous patent suggest a broad gesture area but putting it onto only the bottom left corner of the iPad makes it seem a little more limited in scope. [Patently Apple]
