I have an iPhone iPad mini and iPod nano. Sometimes they're all plugged in to my computer at once. I'd like a dock with a connection sort of like a speaker dock. Meaning rather than cables everywhere you have maybe one cable in the back and three ports to set the device on. Does that make sense? It could have three cables going in the back for each device but I'd rather they sit immobilized in a dock device rather than three usb cables if that makes sense. Know of anything like this?
