During an earnings conference call last year, Steve Jobs hinted that Apple had tested several designs for the iPad during its development process. One of these possible designs may have surfaced in a patent application recently approved by the USPTO and now we get to see what might have been.
This patent shows off a Wi-Fi+3G iPad with an extra USB slot for landscape connectivity. The auxiliary USB slot would let you place the iPad in a dedicated landscape dock and dock it in portrait mode while syncing using both slots. Apple holds a patent for the design, but we will likely never see this in an upcoming iPad model. Still, it always nice to see how things might have been.
