Apart from all other cables from and to my pc there are two cables that are connected to the pc permanently with the ends laying on my desk: the cable for picture upload and the earphones. Cables are driving me mad and especially those on my desk. Sometimes they fall down on the floor, the cat plays with them or even chews on them.
After being annoyed with this for quite a while I screwed two hooks under my desk. That's it. These two cables have a nice home now ;-) but are close by when I need them. Sometimes it's very simple.
