I work sometimes from my desk, sometimes from a standing standing at the other side of the room by the window, and sometimes from neighborhood cafes.
I posted pictures of my setup to /r/minimalism a while ago. Note that I have since failed to keep up this system perfectly, but often my desk does look like this. Seeing what I posted has inspired me to deal with loose paper better, which is my main cause of clutter.
