Not only that, but the rating on the power supply is the maximum, not the average. Just because my MacBook Pro brick says 85W doesn't mean it's constantly drawing 85 Watts! (In fact, plugging it in to my handy Kill-A-Watt, my MBP is drawing only 37 Watts right now.)
As it's the only Mac in the house on right now, it would win.
But the likely winner in my whole collection would be the PowerBook 100, which draws only 10 Watts when running using the hard drive, and a night-light-jealosy-inducing 5 Watts when running off RAM disk.
And to go with Quadraman's line of thought, yes. You must take work done per watt in to account as well.
For example, my MacBook Pro may draw close to 80 Watts under full load, while my dual-socket workstation draws closer to 400 Watts.
But my dual-socket workstation can get video encoding done quickly enough that total Watt-Hours expended encoding video is lower for the workstation than for the notebook.
