Single cable dock
Whilst it's propriety, Microsoft, and about as evil as you can get without a fruity logo, I actually love the dock of the Microsoft Surface fondlePCs, it's a single magnetised connector that gives a pair of Thunderbolts, 4 USB 3.0s (I think), Jiggabit Ethernet, and a 3.5mm audio jack. We gave them to most of the senior managers here (we ordered 10, it's a small company) and they greatly prefer them to the old style docking stations. Saves on deskspace too as most of them prop them up against the wall with the keyboard cover closed.
