When it becomes so engrained in life you forget just how magical and convenient it is. I remember getting the iPhone 6 back in 2014 and the woman in my local grocery giving me funny looks and striking up a conversation about how I had just paid for something with my phone! Back then the transaction limit was only £30 so you couldn't use it for everything yet.

Apple Pay is my favourite example of Apple in action; how they turn something other companies did before that was overly complex into a smooth, mass adopted operation.
