Apple is committed to clean energy. I still think that they are on a mission to make a liquidmetal fuel cell for their cell phones and computers as this would be something no other firm will be able to replicate or counterfeit. Keep in mind that Apple is the largest user of fuel cells in the world that is not an energy company. They are committed to this.
I truly believe this to be the future. Another thing that should make us feel good is that some of the new off-the-shelf iMacs are being designed and assembled in the US. The assembly is a big deal if it's being done domestically. This could be the next cycle of engineering innovation at Apple.
