This one is hard because the origional G3 saved apple's butt. It got lots of positive press and did really well. On the other hand the origional iMac was the best thing ever for apple. So, I had a hard time....I chose the origional G3 though because it allowed for the coming of the iMac
The iMac change the world of design. How many things non-Apple have we seen that have semi opaque bright colors? The design style of the 90s will forever be flavored with it.
Like everybody said the iMac pretty much brought back Apple. You have to wonder where we'd be today if the iMac hadn't happened. I think Steve-o would have still pulled it off.
