One thing that keeps on giving for me me is being able to watch some random youtube video like its nothing. I can click on a random 200 view video from 12 years ago and scrub through it basically no latency. Thinking about how every little packet goes up and down the stack and around the world... The whole infrastructure to make it so seamless.

Meanwhile watching a video from an external drive or my wired SMB NAS fails half the time :|
