Military spec electronics exist. Special High-end Audio components with tighter tolerances exist. Electronics require 'burn in' time to settle. These are all concepts many, many people do not understand. Do people honestly think the same components that go into military gear are the same as what you can buy as a consumer? Is the Space Shuttle comprised of "off the shelf" parts bought anywhere? Nonsense.
I never bothered to read fully into the Doomy thing, but I suspect he might have taken the argument way above the stratosphere and some of the ones poking the most fun were either not aware of such things or just figured him a loon. lol But I do remember reading, back before the A1000 was released, talk about "military grade" components being used in the Amiga line. I guess to an extent, a ceramic encased I.C., which can dissipate heat much better than a plastic encased one, would fall into that category. Circuit boards, they way they are etched and their traces are not all equal either. A lot of my high-end audio use glass or a glass composite instead of the plain old off the shelf fiberboard used in MOST consumer grade crap. Why? Because it's more rigid, handles resonance better and is less conductive to name a few attributes. Circuit boards also vary in thickness. I guess after a certain spec, that too would be considered "military grade". There's a ton of varying standards to be sure.
