I have both a Jetway and a zotac ion N330's as diskless systems.  Both
use approximately 25-30W according to a kilawatt type meter.  Of that,
the power brick uses 9W in each case - even when not plugged into the

Mind you, thats still a fraction of the recycled desktop systems they
replaced.  Its now been around 2 years since I got the first one, and
its played everything Ive put at it (i.e., what I want to watch).  By
the time the off-air etc comes up with something it wont play, it will
easily be time to replace them anyway.  In the meantime I have been
watching on power saving hardware, that at the time cost less than
non-power saving alternatives.

Also, I find that power saving on non-atom type systems is not the
easiest thing to get right, and keep it right - are you getting what you
think you are getting?
