As individuals, our data sample size is much smaller than a large company’s. So what may be true and obvious in our own spheres may not be true (or not relevant enough) in the wider scope. And sure, no company has perfect vision and analytics, but from their track record, Apple seems to be right overwhelmingly more often than wrong, hence their success. Not to say that we can’t question and express our opinions. Just pointing out (as unpopular as this will be) that statistically speaking, it’s very unlikely that any of us can say with certainty that we know better than Apple (or any successful company) what is best for them on any particular point.In this instance, "should" as in it makes sense for the company AND for the consumer. People would be all over that. It's not like people are spending an extra $1400 just to get a bigger screen. I know a number of people that stick with windows laptops because they don't want a little 13 screen after many years accustomed to using 15" laptop screens.
Edit: Apple famously thought they knew better than the consumer regarding phone screen size, but they had to admit they ****ed that up. I really do believe a 15" Air as good as the current Air, would sell like hotcakes.
But I’m all for expressing wishes. It’s not nearly as influential as voting with one’s wallet, but the noise could feasibly help give meaning to low sales numbers.
