Having bought a new desk I decided to sort out the mare's nest of cables that had accumulated behind the old one over the years. I was amazed to find that I had 8 wall warts just for this relatively small area. This does not include the 7 chargers used elsewhere in the building for mobiles etc.
I really wanted to rationalise the various extension strips I have under the desk and arrange to put the sockets somewhere more accessible. The only options I can think of at the moment are either two 6 gang switched extension leads fastened to one end of the desk or four MK 3 gang switched socket outlets recessed into the end panel of the desk. At least these would cover current needs and allow for a couple of spare outlets.
