You don't carry the disc or plug anything... It rests on your desk/nightstand so you can place the phone there without having to plug anything, or unplug anything to check a notification or run to a meeting. It's not a fundamental change of course... battery lasts long enough you probably could just skip charging instead (other than the night-stand case) and it's only slightly more convenient than plugging in a cable.
