This was a very interesting article, that raises almost as many questions as it answers.

A couple of things I would like to see someone try to address in a fashion similar to this article:

1. What real longevity impact does power and sleep cycling really have on modern hardware?

2. How much impact to overall power consumption do the power states of the individual system components have? For example, does having the OS power-down the hard drives during periods of inactivity make a significant difference?

3. I assume that the CPU isn't the only potential differentiator that one could make in a system for power consumption tuning. How large a difference in power consumption would different video and disk subsystem have (e.g. Nvidia vs. ATI)?

Great article though. Makes one think.
