I just got back from Macworld Expo in San Francisco. While there, I came across this device from Kanex – Sydnee (http://www.kanexlive.com/sydnee). It's essentially an iPad charger for a family or small office.
With one plug in the wall, you can set up to three iPads (or other iOS devices). You also can plug in a fourth device. You can keep things nice and neat without having a total cable nest in your family room. The system will auto-detect when devices are charged and then shut off the individual port (while other devices keep charging as needed).
The device is supposed to start shipping in March (at least according to the booth person I talked to). You can sign up for early info on the product's page. It's list for $149 at this time.
