Google in superposition of using, not using quantum computer

[nsane.forums]

Way back in 2007, a company called D-Wave systems demonstrated... well, no one is really sure what it demonstrated. D-Wave claimed it was a quantum computer, but if that was so, then this tiny company managed to produce something that was way beyond anything that had been seen in a research lab, despite their large budgets and talented scientists. Since then, D-Wave has occasionally released new claims, but, most importantly, no actual information that shows that whatever it has built is a quantum computer.

As a result, I was quite surprised to find that search behemoth Google had started working with D-Wave on quantum computer-based search. Among the questions that puzzled me were why Google would be interested in quantum computing, and, assuming that they are, why would they work with D-Wave?
