Usability in Hardware

I have a TC Electronic BMC-2 monitor controller, that I use and like, for controlling volume on nearfield monitors and headphones in my studio.

But it has a usability problem. We talk about usability in software all the time, but here’s an example of a hardware usability problem. Here’s the back panel:

Whose brilliant idea was it to put the headphone jack under the power jack? When I use it, I’m always in front of the unit, reaching over the top to control it. Which one of these jacks is likely to get plugged and unplugged more often?

Maybe the BMC-2mkII will reverse the positions of these. I doubt it will be a free downloadable update though.
