I have used a Microsoft Surface Pro 3 work computer for almost more than a year now. My desk at the office have a docking station with a keyboard, mouse and headset with microphone connected. I also have two 24″ monitors connected in addition to the screen of the Surface. The docking station for the Surface Pro 3 only have 1 mini display port but a USB 3.0 graphics adapter was all I needed to set up the second monitor. My Surface is not joined to the domain and is treated as bring your own device.
Here are my experience with my Surface Pro 3 work computer.
