Somehow, I don't think we're going to see real quantum computing for quite some time yet. We're too early in the research, and there is (as per usual in the industry) far too much hype for what actually exists right now.
I compare what D-Wave has now to a 2-D graphics "accelerator" card for an early computer, with what I expect "real" quantum computing to resemble about as much as a modern NVidia or ATI card's processor.
I have much greater faith in fusion power research at this point; many important steps have been taken during my lifetime of reading news about it over the past 30-35 years. Sure their promise back then that we were "about 30 years away" was the same as the quantum hype now, but the time and effort and, most of all, the learning that has been done is incredible. I have a gut feeling we're very close; I hold high hopes for ITER's results.
