Sure but D-Wave is pretty much a "Silver-not-gold" level quantum computing device.

They are, more or less, clear that they aren't doing real, general purpose quantum computing but special purpose quantum computing.

It would be great to have a general purpose quantum computer. D-Wave is spec'd as such, sorry.

It's possible that D-Wave is a clever special-purpose classical machine that's just being hyped as a quantum machine. But the linked article seems to give good evidence that D-Wave is what it claims to be; a special purpose quantum computer, which is indeed different than a general purpose quantum computer.

One thing to think about is that D-Wave may be going just a little beyond what's possible but, apparently, using quantum computing to go that little, they learning something possible interesting about creating a quantum computing device.

I don't have any issue with the fact that it is special purpose, I have a hard time calling it a success before it can be shown to be better than any known classical approaches at something.

I love the fact that they are trying and are spreading awareness of quantum computing but I take issue with some of their claims. They have a long history of making unsubstantiated and sensationalized claims. They also have a portfolio of patents many of which were arguably discovered by someone else or are overly broad.
