At one point, before we virtualised everything, I had a custom desk built in an L-shape. Instead of a desk and a return, I had the refurbishment team put together a desk with two desks instead. It gave me two sets of drawers, two computer cubby holes and the gap was too small for the horrible keyboard adjustable shelf that kept hitting your knees, so they replaced it with a fixed surface instead.
People laughed.
Colleagues sniggered.
Then they wanted one too.
Now I have a mobile lectern with an iMac clamped to it. Height adjustable, wheels, enough space for keyboard, trackpad and USB hub. I move around my office as the mood or light takes me.
