Sure, I'm all for this. Less body parts being sold is always a good move. I just think we need to keep in check why corporations SOMETIMES act ethically.
As much as I hate Apple (and like beef and leather), I suspect a bit of work went into making it financially viable. Maybe they've worked their synthetic material to be as good and cost effective.
But yeah, there's the chance it's all marketing and they've merely replaced the word "vinyl" with "vegan" and called it a day.
Maybe they want to move manufacture to India where the cow is sacred. Who knows.
