I mostly agree with you. But a tiny devil in my brain wants me to mention that the slogan "Apple ][ Forever!" was introduced AFTER the Mac came out.
An even tinier devil whispers that Apple didn't pull the plug on Apple ][ until many years later. And at that point people were surprised to hear Apple was still making them.
"My point", says the first, larger devil, "is that in 1985 everyone blindly trusted that the Apple ][ wasn't going anywhere. Maybe that's what's happening with the Mac now."
"Like you have any special insight," scoffs the smaller devil. "You're just playing devil's advocate. Someone says something, you propose the opposite."
"Me?! You're LITERALLY a devil's advocate! I'm just trying to help my good friend Matt make sense of the world."
"Some friend! Your constant second-guessing is the reason he can't talk to women!"
"STOP STARING INTO SPACE AND GET BACK TO WORK" shouts my boss.
