Update: We just got our hands on a working engineering unit of the PadFone. Eagle-eyed readers might notice the odd tweaks here and there on the outside, and we also spotted three new mysterious contact pins along the USB and HDMI side of the phone. The product manager was away so we couldn't get an answer for what the pins are for, but we'd imagine they're for an external antenna. After the break you'll see a demo video of the PadFone switching screens as it slides into the tablet -- we've been told the final product will be able to switch even faster, so here's hoping ASUS can keep its promise.
