This will get even better with USB-C and/or Thunderbolt. Just sit down and with a single cable, get monitor, power, network and peripherals. (Almost) regardless of laptop make & model.
No it won't get better. On a dock, you have to connect exactly zero cables. Just place the laptop on the dock. That's it. No cables. No connectors. The bottom of the laptop has a connection which touches the pins on the top of the dock surface.
