The Green Lounge have got their hands on a comprehensive power meter and used it to test the power draw of a Zonbu unit. The power meter comes with a software package that allows you to use the data it collects to predict the average monthly power consumption, and by adding in your cost of electricity, you can predict the average monthly cost to run a device. I was shocked at just how cheap the Zonbu is to run. I am looking forward to seeing the results of this test done on other PCs for comparison.
