It’s not the jack itself, but rather what it represents. The ability to simply and easily do what you want with a device you paid potentially thousands of dollars for, and it was taken away for no better reason than to save a few cents, or mimic a more successful company that wanted to save a few cents. Similarly, easily swappable batteries. The battery is likely the first component in a device to die, and when it does fuck you, buy a whole new phone. I used to never put my phone on a charger; I had two batteries and I’d just switch them out every morning, easy and simple. That feature was taken away by greedy megacorps who refuse to make a product that I actually want to buy, instead I have to settle for a worse product that costs more than it needs to and does less than what its replacing.
