Everyone needs a bag to carry their stuff in, and many bags now come with special features for consumer electronics devices, like padded compartments. For me, the ultimate bag is the PowerBag, which comes with a built-in battery. PowerBag sells backpacks like those pictured here, messenger bags and briefcases on rollers. Each has internal cables to connect devices. There might not be enough, but there's a USB port so in the worst case you can attach a hub and charge more devices from there.
