what I would like is wireless power and data while the gadget is out of the packaging. A phone, camera or tablet could be totally environmentally sealed; filling the voids with heat-conducting gel would avoid localised heat build-up, and one would end up with a tough, go-anywhere device.
Of course, there would have to be enough memory in there for general use, and the battery would not be replaceable. The technology is already out there (inductive charging, comms via wifi, bluetooth or wireless usb), it just needs bringing together. and some standardisation would help, so I would not need a different docking/charging station for each device I own!
