I agree, but I'm going to defend the wifi case a little. Ethernet doesn't work if you're using a laptop, because it defeats the purpose of having a portable computer in the first place. You either have to be able to work offline, or you have to stay next to an ethernet plug.

I said above that wired headphones have infinite battery life. I suppose I could say the same about a desktop computer versus a laptop, but I don't think that would be fair.

FWIW, the proliferation of video calls over my laptop has pushed me back to wired internet at my desk. Combined with wired headphones - I have so much less latency than any of my co-workers. It's nice to not have to play the "can you hear me" song and dance.
