I think either way this is a good move for these companies. It is a good way for them to diversify their product and still meet the needs of their entire audience; gamers can still game off their gpus and miners won't be buying up all of them and will be saving on electricity this way. I think this is a good move, even if the mainstream adoption isn't entirely there; there is one way to revolutionize the market and that is to be the first at creating it's leading innovations. I hope this brings a little bit more of an even playing field for those who can't afford expensive asic miners, or who would want to build their own rig not just for mining rewards but for accomplishments. Not sure, but I like it either way!
