Compare the two keyboards:
Older generation
Newer generation
You can see in the first image, the keys are bulkier, thus, it would've required more resources to produce. But in the second image, the keys are almost not apparent at all. I've actually used the keyboard and it types very, very well. Apple has yet again, figured out a way to use less resources and make a light-weight and easy design for their consumers. They have replaced their plastic resources with aluminum. Aluminum is much easier to recycle and it produces less waste.
Other than the keyboard, Apple has also pushed its green initiatives with the iPhone 3G's packaging, using potato-starch based products and avoiding plastics altogether.
With all the rave about the iPhone's these days, Apple has successfully created a popular, high-tech object while still keeping it's promise to our planet.
