According to an eBay listing found by Mac Rumors, it confirms an ancient rumor that Apple had at one point considered an iPad with two dock connectors.
The iPad prototype on sale looks authentic, and is unique in several aspects. Two functional dock connectors, one on the side and one at the bottom. It also has a special Apple diagnostic software suite called Switchboard.
The starting price is a whopping $4,800, and the “buy it now” price is $10,000. Yikes. But why are we dwelling on the past? One dock connector is more than enough.
