The mean power consumption is significantly higher than the median because the worst offenders are drawing tens of watts in standby mode. For example, this 4 year old Philips TV that is at 30 watts in standby: http://www.supportforum.philips.com/en/showthread.php?15754-...

Cable/satellite boxes also frequently draw multiple watts in standby or "off". If every bit of consumer electronics were as thrifty with standby as your TV, it wouldn't be a problem anymore.

(I'll add: my iPod Touch can "wake up" instantly when I interact with it after days sitting unplugged, and that's drawing from a tiny battery. Even 120 mW is far above the lower bound of what's necessary to build a complex device with fast wakeup upon user interaction.)

(Second edit: the power converter that started this discussion is obviously targeted at much lower power applications than even an iPod, so it's not really relevant to anything that can be plugged in at home.)
