I have a cabinet in the front room where my "gadgets" live when not in use. 505, YP-P2, camera, Tom Tom, labeler, DS lite, phone cords, flash drives, etc.
Nothing else is allowed in there but gadget stuff.
I also have a wooden box inside the cabinet that holds all the cords. Each cord is in a zip lock baggie that is labeled. (ie, YP-P2 to PC, camera to PC, camera to AC, 505 to AC, 505 to PC, etc.)
A surge protector strip is also inside for AC charging that is out of the way.
A bit much probably, but it works. I don't have to think or look for anything (it's all in one place). Just grab the correctly labeled baggie and plug it in.
