Performance per Watt: Hey, I already know it’s important, don’t I? (The intro, part I)

What is performance per Watt?

Performance per Watt is pretty straight forward when you first look at it. Then you begin to sink in the quicksand you’ve blithely walked into. The panic sets in as you sink lower and lower. Eventually you decide to ignore the whole complicated mess and go back to saying to yourself how straight forward it is. Of course, deep within your heart of hearts, you know that it’s not.

For most of us, performance per Watt is nothing more than how much our computer can get done on a given battery charge.
