Its annoying to see supposedly technical sites like GigaOm post articles with obvious, and significant, poor use of units.
In a recent - and otherwise good - article on Zigbee versus WiFi, they state "ZigBee systems consumed just 0.39 watts over 24 hours, compared to Wi-Fi’s 0.87 watts over the same time"
While the relative saving of 55% is interesting, the statement of actual consumption is meaningless, and can be read two different ways - its either a consumption of 0.39 watts, or its 0.39 watt-hours/day that is a factor of 24 difference.
When the editors of technical sites can't pick up things like this, its hard to expect mainstream media to get it right.
I've commented on that site, and would encourage readers to similarly comment on obvious numeric errors until the editors learn the difference between a watt and a watt-hour.
