It was interesting to hear apple state that one of their goals for building products was to make them last longer in order to minimize waste. People often accuse hardware manufacturers, including apple, of intentional obsolescence. I am interested to see if they actually change anything about their process, software and hardware, to put any weight behind this claim, or if it is just marketing doublespeak.
In the same section she said they were already using recycled tin in the control boards, and their recycling programme had been improved too.
To be honest the sustainability part was the most impressive of the whole keynote, and is a reason I'll continue to be a loyal Apple customer.
