That's a fascinating insight into the clean desk obsession.
My desks are always a mess, but I do so much from them they have to be. When it's time to do screen work I focus on the screen.
I tend to keep my desk area tidy - keyboard and mouse is about all thats needed. Headset i leave on top of my laptop until needed
The only other room I need is for test kit - macbook air, win 10 laptop, 2 or 3 iphones. Thankfully I bought a pedestal and keep all the test kit in
