It works just fine for me. I have played a few games that need a keyboard and trackball, so those work great docked. I used to have a setup with external speakers and a monitor connected to my dock.

If I ever get a Steam Controller I am sure I will play docked even more. My most played game is No Man’s Sky, which I mostly play on a stand for my iPad. It puts the screen a little higher and allows it to stand up when I am not holding it.
