Yeah, those were really nice models, those iMacs released in the summer of 2000 (Indigo, Ruby and Sage).
After all those months (all of 1999 and the first half of 2000) with the bright fruit colors and accessories, the deeper, richer colors in that new line-up (especially the Ruby!) were a cool change.
I always thought
the Sage model was gorgeous. Just the slightest hint of cool mossy green. Those models just didn't seem to make much of an impact, sadly. And eventually gave way to the
Blue Dalmation and Flower Power designs.
