no no no no no.
The things that are bad for the environment are also used intensively in the PRODUCTION of materials used in computers, the Mo-Boards, the Processors, anything solid state. Sure the things contain trace amounts of Lead and other crap but they aren't nearly as harmful to the environment as, say MAKING a microprocessor. Thus, I have no idea why on Earth Intel isn't #1 based solely on the sheer volume of byproduct they produce.
And if Greenpeace is going after PC makers, Dell, again just by their VOLUME, dwarfs Apple in toxins used in their products. Apple, however, makes a noticable effort (i.e. free disposal w/a new Mac, iPod) to ensure that people don't just toss their computers in a way that will hurt the environment. Dell has a service as well, but it isn't free.
I think Greenpeace just spun the roulette wheel and it landed in Apple's disfavor.
I care about the environment, but Greenpeace is out of hand. It's the little things like free disposal that make the difference. It might be what keeps some people from slipping pieces of old computers in their trash can week-by-week.
... oh come on, like you've never done that...
