Does it really matter" is what I used to say too. Then my wifi went out for a full day and I changed my mind fast. A solid connection is the difference between getting things done and just staring at a loading screen.
Totally feel you on this one. I remember last year trying to join a big work call and my connection kept cutting out every two minutes. I was just sitting there frozen, missing half the conversation. It's the kind of thing that makes you want to throw your laptop out the window. A weak signal can wreck your whole day, no matter what you're doing.
