I'd still say getting 7 years of free OS supports for hardware is pretty incredible. All-in-ones like iMacs are always going to be wasteful on the environmental side of things faster because displays will outlive the usefulness of the rest of it by a large large margin.
At least Apple does try a bit to be a responsible recycler and you can always take your old hardware to them.
