Being greener is not all about saving power. The LED displays get rid of mercury, which has been the biggest downside to CCFL backlights.
Steve jobs quoted that all new displays will be LED within a year, so why not add them into a major redesign. Especially if you can make your enclosure thinner and sleeker by incorporating them.
Ok, my expectations for LED iMacs are back online. I still hope that since they run cooler, they can put in some desktop components.
