"Rather than the mechanism being inherently at fault, its issue was that small amounts of dust or debris could seriously disrupt the keyswitch operation - and who lives in an environment without dust?"
I dont know, I think that sounds like the mechanism is at fault, because it wasn't designed to meet the operating specs for the environment they knew it would be operating in. The craziest thing is this was self inflicted for no real reason, the change in keyboard design didn't even give them that much of a change in case height, or a huge weight reduction. Apple does what Apple does sometimes I guess, but they never admit that they were wrong in the first place.
A Narcissist's Prayer
That didn't happen.
And if it did, it wasn't that bad.
And if it was, that's not a big deal.
And if it is, that's not my fault.
And if it was, I didn't mean it.
And if I did...
You deserved it.
