Personally, I am not too bothered by any issues this case may have.
What the recent keynote demonstrated, is that Tim Cook has a very clear big picture vision that he is using to guide Apple. We see how well-rounded he is as a CEO, he is clearly way more confident in running the company compared to when he first took over the reins, and I will say that I am impressed by how he is redefining the role of a fortune 500 company CEO's role in today's modern society.
The issue with leather cases isn't in the material itself, but the amount of leather that is needed at Apple's scale. I feel this goes to show how committed Apple is to their own self-imposed goal of being carbon neutral by 2030. It looks like the finewoven fabric will not be for everyone, and I suppose it further demonstrates how difficult it is to balance both profitability and being environmentally conscious.
A crappy case will not make or break the company's fortunes.
I have also decided that I am no longer as interested in firebrand CEOs who take the stage and talk big about product releases (and subsequently proceed to not deliver). Steve Jobs was one of a kind, he was the right person to lead Apple then, just as Tim Cook is the right person to lead Apple in a world where their biggest threats are not other tech companies like Microsoft, Google or Samsung, but world governments, an increasingly polarised society, and strained political ties. I like having a stable hand at the wheel and knowing that the company is being run like a well-oiled machine and the products I love to use will continue to be supported and improved on for a good many years to come.
