I don't want to wait 6hrs to download a game patch that's 40gb or whatever because that's sadly the norm. With 1gbit I can do anything and it doesn't induce latency or cause connection quality issues with anything else because no one thing can come close to saturating it really, with a few exceptions (Steam being the main one). I can also seed at high speed to private trackers. It'd be an effort to max out a 25gbit connection at home that's for sure.
