As someone else already mentioned, it's sold out
But... this is the first picture I've seen that shows the other end of the cable: it's a standard USB connector. Which, to me, is a dealbreaker, even if it is on sale at some future date. Doesn't that limit the amount of charging current that will be available to the port? I had original assumed that the other end of the connector would be a higher capacity power source. My first tablet, a Toshiba Thrive, has a custom (barrel) connector, but the tablet charges much more quickly than my Nexus 10 when I'm using that source (you can also charge the Thrive from the USB connector, but it's slow as mud)
Pogo charger users, please correct me if I'm wrong about this.
