Totally disagree with the premise of the article. Every metric tool that i know of that shows cpu utilization correctly shows cpu work. Load on the other hand represents cpu and iowait (overall system throughput). Io wait is also exposed in top as the "wait" metric. An amazon EC2 box can very easily get to load(5) = 10 (anything above 1 is considered bad), but the cpu utilization metric will still show almost no cpu util.
