I've seen a lot of articles about haveing a landing zone to put all your stuff. The big problem I see with a lot of them is they suggest a table in the hall or by the door or whatever so your suff is all sitting out in open view looking cluttered or getting knocked off by the kids/pets. I simply stuck a second shelf about 1 foot above the existing closet shelf and moved everything up and put a power strip in there.
one of the other things I've done to eliminate clutter is to not have a place to sit at the computer. I never liked that idea anyway of having a computer desk stuck in the corner or in its own room wasting space and getting cluttered. So many people have one and it becomes a place to stack bills and papers and crap. I switched to a laptop in the late 90's and went external with all my other things by putting a dvd burner in a USB encloseure for example. Then everything goes on a shelf or in a bag and gets put away. I don't sit down and "pay bills" or waste other time with stuff like that, I go paperless and when the e-mail comes simply sign in my bank web site and schedule a payment.
I'm going more and more wireless with all my gear and consolidating things down. I see no need to carry a cell phone, pda, ipod, etc when I can buy one pda phone and carry everything there, pop in a SD wifi card and synch with my little server without having to sit down at a desk and have a place for a docking station and cords and papers and junk like that.
So for me that closet shelf fits in with my overall plan of eliminating clutter and waste.
