Are you shooting in tethered mode frequently?
Having two or three cables hanging out from the side of your camera?
Well I always do, when I shoot in house, all the product "studio" sessions are shot tethered.
This involves a USB cable, an AC to DC coupler cable and sometimes a Wireless Remote cable.
Trust me, the most frustrating part comes when once a while I accidentally step on one of the cables, and connection with the PC is lost due to an unplugged cable.
