If there is one thing that can't be reused to it's full effect, it is electronic cords. Each piece of electronics comes with it's own cord and they never seem to be the same when the update the item either and when the plug is lost the electronics can become worthless or when the video camera dies, the plug must to tossed as well; if you can find it.
My solution to making electronics and cords last as long as possible comes via my Sharpie. The minute I pull the new item out of the box, I mark the plug. This way, if the cord isn't paired with the item, I will be able to find it amongst the other cobweb of cords.
This is also very handy for when you have cords plugged in to a 12 count surge protectors. Don't want to unplug the tv, but need to reboot the cable box? Once you get the right one, write on it C.B in a small corner and you'll be ready for when the phone tech tells you to unplug the power to your cable box to reboot it.
Now when you open your desk drawer you will know which cords go to which electronics and will be able to declutter faster when a piece of electronics dies.
