Exactly. It's silly to turn one's nose in the air and declare Macs Were Better Before They Were Made in China, because the chances are extraordinarily high the very Macs you're thinking of were (gasp!) Made in China. The problem isn't China; the problem (when one exists) lies in Apple's poor quality control. *Every* major company makes their gear in one of the same Chinese factories; the difference lies in how much any of those companies cares about producing quality gear than they do about cutting costs. Let's leave xeno (and xino) phobia out of this, folks. China Did Not Make Your Mac Suck; Apple did.
Absolutely. For Macs or cameras or anything, quality is not dependent on where they are made.
The components are are made on automated lines. Workers aren't soldering things together, a really fast machine is. Assembly line workers just zip these components into their waiting cases (which came off another automated assembly line).
It is the design and specs that determine quality. Apple could simply bid out a hard drive and pick the cheapest one, or could specify that it must last for so long, etc. with some guarantee.
I suspect that the Intel switch means that Apple is buying more generic parts, the same parts basically that other companies buy and that these are all cost-driven. In the old days, when Apple hardware was specific to Apple, there may have been more stringent specifications since it was custom made anyway.
In the end, if Apple does a good job of designing a product, chooses good components and then does a good job of testing and quality control on all of the components, then the product will be good. If not, well then they are just hoping.
Now, China is facing its own labor, environmental and quality of life issues and companies there are being shut down as they can't compete with Indonesia or Vietnam. It is only a matter of time before your Mac is labeled "made in Sudan".
So, finally, if a Mac falls apart it is entirely Apple's fault because they either didn't design it properly, speced out overly cheap components or did not do a good job of overseeing everything. Where it was made means nothing in terms of the quality.
