So true, yet I remember at the time there was so much bitchin' 'n whining going on about the change from 30pin to Lightning: "how dare Apple, we've only had this standard for 8 or nine years", "Apple doesn't care about their customers", "now we all have to go out and buy new cables and accessories", blah, blah, blah, on and on ..
