It is much faster to load up on my monitor and flawlessly disconnects with no shut downs and glitches. But the new docking station really solidified the performance in the docking experience. I upgraded to an SP4 which was a huge improvement in the reliability side of things. My old dock was giving me trouble like causing shut downs when I pulled my SP3 out with certain apps running. I had the older SP3 dock before and i thought that this would be a downgrade because I like how easy it was to plop the surface into it as opposed to fiddling around trying to fit a connector into the side. Overall, this is an excellent Surface Pro tablet computer supporting device, though Microsoft should consider a one-box design for the their next Dock Station, and a longer AC power cord.

The two-box Microsoft 1661 Dock Station design is also slightly more un wieldy to set up than the original one-box power brick, but likely an equitable trade given all the added connection functionality. Total weight of the Microsoft 1661 Dock Station, and its two-box design, is more than the weight of the original power brick that ships with the Surface Pro tablet. The Microsoft 1661 Dock Station is made up of two parts: one box for all the tablet computer to accessory/peripheral/power connections and a second box that functions as the power brick for the first box. In addition, the Microsoft 1661 Dock Station functions as a powered USB hub that can recharge your cell phone(s).

The Microsoft 1661 Dock Station manages all the Ethernet/USB/video-monitor connections of your accessories and/or peripheral devices, while simultaneously charging, and doing all this with only ONE connection to your Surface Pro 3/4 Tablet.
