Agreed. Except the part about 4:3 video. That's just upsetting to think about. "Widescreen" (anywhere from 16:9 to the 1.85:1 often used in movies) is acceptable, 4:3 is far too cramped for a pleasant viewing experience.

If you're watching on anything other than certain laptop screens, you're likely to have pillarboxing which is just wasted space that could be beautiful landscapes, helpful information, or artistic framing.
