Bad idea. The Surface connect port is so much better than USB C. It's nearly impossible to find a USB C dock with power and 5 USB C ports and 3 USB A ports. That's what I have available with the new Dock 2. I have two monitors connected, a mouse, and my cell phone are connected too. I connect with one cord. I still have both type C ports on the front of the dock open and both the type A and type C available on the device itself.
I gave my original dock to my daughter with my Surface Pro 5. She loves that her monitor, keyboard, mouse, and DVD drive are all so easily connected with one magnetic cord.
No reason to get rid of it. I love the better idea of making the port available to all Windows devices!
