I'd have hoped that in 20 years, it might be playable enough... But I'm definitely not an expert in this field.

In fact, any task which can be broken up into parallel tasks would be sped up considerably by quantum computers. And those tasks aren't rare - think of modern GPUs with thousands upon thousands of cores. A quantum GPU would probably mean that display technology would be the main bottleneck in graphics quality. And of course, quantum CPUs wouldn't be useless either.
Nothing you just said makes any sense and you have no evidence to back up your assumptions. I hope you understand if I'm going to take the word of physicists who spent their lives studying and working on these things over yours.
Well, that's what I was brought to understand. From sources not exactly originating directly from researchers specializing in the field of quantum computing... Anyway, I'm a poleaseman (=P), not a quantum physicist, so I may well be wrong. Forget what I said in that case.

The liquid helium isotopes needed to power the heat pumps are extremely expensive, don't last very long, extremely difficult to transport, and extremely dangerous to use. And even if you extremely careful and do everything right like a proper scientist while operating the thing it could still easily experience decoherence and become worthless in an instant.
By definition, if they become affordable to operate at home no part of it will be expensive. And if you're supposed to change it often, it should be affordable to do so.
That doesn't mean what you say untrue, but rather means that quantum PCs aren't going to become fully affordable and reliable for quite some time. If they do, however (which may never happen - IDK), then by definition it shouldn't be harder to operate than a traditional PC.
