I'm pretty sure Apple goes far more for the green agenda than the old PC makers ever did - even taking into account the tiny savings you get from the few people that upgraded or repaired their laptops in the past.
Sure, Apple recycles some of the parts of the device, but environmentally, it's much better to support and repair a device than it is to simply crush it and recycle it.
