Really? I consider myself pretty economical, but I throw out much more than a few lightning cables worth of waste in a given week (probably more on any day even). Would they even really be noticeable in your trash can?
I don't know that I had an argument, more of a question of if a couple of cables would even be noticeable as trash.
I'd say my argument is purely logistical - one less cable type would be quite a boon to me personally. I have a few lightning cables that only work with exactly one device that I own - my iPhone 11. I'm quite happy with my phone, and perhaps ironically for Apple, the best way they'd have to get me to replace it would be to make a new one with a USB-C port; it's the feature I'd most like at this point.
I'd also love to see touchid make a return, but I don't see that happening.
