In our process to turn our company GREEN. We are taking every step necessary to do our part in saving the environment. That included upgrading all of our computer systems to shiny new MacBook Pros:

MacBook Pro 15.4" - Unibody Aluminum

According to Apple Inc., they are the greenest family available:

“When we designed the new MacBook, our designers and engineers set a goal of making not only the greenest notebook Apple ever produced, but the greenest family of notebooks. So every new MacBook has been built using materials that are highly recyclable and free of many of the harmful substances present in other computers. Apple engineers also designed the software and hardware to work together, in order to maximize energy efficiency and minimize the carbon footprint of the MacBook. Even the packaging was reconsidered and reduced, producing smaller boxes to ship and less material to recycle. The result is exactly what we hoped for: the greenest family of notebooks ever made.” - Apple Inc
