Seems like an opportunity for a company to develop a power adaptor for USB-C that includes a quick-detach, magsafe-like connection near the USB-C plug end.
Another opportunity is to create a docking station that plugs into USB-C and offers all the ports you would normally use on a desk, so you can easily and quickly transition from laptop to desktop by plugging one cable into the USB-C port.
