(snip) I believe that the power savings by turning off vampire devices can pay back for the strips in a short time. (/snip)

Rather than relying on belief, your article would have been much stronger if you had included some concrete numbers on power savings. A table with some simple assumptions:
- some typical electricity prices across the country
- Power use metrics for some new and old devices (both powered on and sleep mode)
- assume some time regimes, ie on for 9 hrs per day at work, on for 5-6 hours at home (ie 6pm to midnight)
- calculate the costs and payback period.

The manufacture should include an online version of the savings calculator so people can plug in their local numbers.
