Yeah I absolutely will use that. I unplugged my Ducky almost once a day for various reasons. Usually to do some quick test key presses or swap caps, and not worry about where I was in the OS and what havoc I'd cause (lol, havoc is a little strong )
All my perifial cables coming out of my tower are velcroed together to stay neat, if I wanna do a quick wipe down of my desk for dust then I'd have to undo that, unplug the Filco, move/clean, then reverse. Pain in the ass.
And I doubt I'll make my filco a mobile board and take it other places, but still would be nice to not have to worry about messing with my towers cabling to do so.
As esoo said, I'd to mod the cable and add sleeve, but my main reason is pure functionality
