Whatever your beliefs about the morality of harvesting embryonic stem cells from embryos, the stem cells that we'll get from this process (if it all works out) have the distinct advantage of being able to carry the same set of genes as the target recipient. This eliminates nasty problems with rejection and immunosuppressant anti-rejection drugs.
And it looks like a process that works around moral objections for almost everyone. (I say almost, because there are people who have moral objections to any form of medical treatment. But for the vast majority of Americans, this method of generating stem cells should be just fine.)
Better living through biology. :)
