I have a ThinkPad 520W. It's powerful enough to replace my desktop. But a 15 inch screen is not enough. The MiniDock allowed me to add two external 24-inch monitors alongside the laptop's display. Now I have three desktops. I usually keep a dozen windows open at a time, so three screens is a great feature. I figured I would turn off the laptop display and just use two monitors, but I like having three views. The 520W has a USB3. MiniDock adds more USB3. It's not that important to me at the moment, but I suspect it will be next year. MiniDock adds more features: audio output, Ethernet, etc. It's very easy, just undock and go, then dock back and plug everything in.
