Apple has filed few patents linked with iPad 2′s new Features Patently Apple uncovered some patents that provide a peak into the future of the iPad. iPad is getting a second 30-pin dock connector port on the left side for landscape/horizontal docking.
The 30-pin connector could possibly be a mini-HDMI or USB port but in reality that’s actually the sim-card slot/tray from the current iPad 3G.
Another patent is for something called a “Smart Bezel.” That appears to be a touch-based quick access key. A part of the bezel will be touch sensitive and you can assign that spot a particular action.
And of course they are adding Dual camera to it for Photos and Videos. And as a part of thier strategy – “Facetime on every iDevice”, its coming to iPad.
The camera hole is identical to the one seen on the current iPod touch with a front-facing camera. But the possibility of it being a iPad’s ambient light sensor are also not less. But looking at all previous iPad SDK’s hints, its evident that its a camera.
