We're very used to Apple prototypes showing up on eBay. It's not often that we see unreleased iPads get the auction treatment, however, which makes a new listing that much more interesting. A 16GB WiFi version of the original iPad has popped up sporting a second dock connector on its side, a feature that we'd previously only spotted in Apple design patents. The advantage, of course, would be to keep the iPad powered and synced while it's playing a favorite movie in landscape mode. While we don't know how one aaps69 managed to get hands on the tablet, there's some clear signs that the seller didn't just carve an extra hole in the aluminum for kicks: the slate is running the familiar SwitchBoard tool that Apple uses for in-house diagnostics, and there's a raft of old and incomplete part details that suggest this particular iPad was never meant for store shelves. We'll likely never know why Apple left us in a land of solo dock connectors, but we'd take a peek at the source link before it's gone, as more recent Apple prototypes at auction tend to return to the source quickly.
