Two things here to unpack...
First, I, personally, would never presume to tell anyone how they should spend their hard-earned dollars. Fact is, not every shopper has the budget even for the lowest-priced 24" iMac. If one's budget can only buy 1080P then that's what will get purchased. And there are plenty of sub-$1K iMac knockoffs for sale this holiday season for which Apple has no competition.
Second, as an investor and shareholder, "blind faith" is not in my lexicon. I never presume to trust that anyone "
knows what they are doing" in any venture involving human beings! LOL And that goes for the tens of thousands of folks at Apple. They're no different from any other enterprise in this regard and they are not immune from making incredible blunders.
