I disagree. There are a number of options here, but my personal favorite is the Belkin TB2 dock. Plug in two cables (power/TB) and I have three external screens, wired keyboard, multiple USB3 plugs, gigabit Ethernet, and a decent audio line out.

If you prefer something exactly like a dock where no cables are involved being plugged in manually, there are several solutions available. Henge Docks, Landing Zone, and BookEndz are some examples.
