EcoButton is saving me money and carbon

I use an EcoButton attached to a USB port of my computer. When I leave it - to go to the loo, have lunch, answer the phone, feed the dogs etc. - I tap the EcoButton and it powers down the PC. When I return another tap returns me to where I was, with everything open at the same place. It also keeps a tally of how much carbon and money have been saved, based on current energy prices.
