Your argument actually shows that weighting by volume is a necessity if you're trying to represent people's experiences - which are driven by the likelihood that each given video they want to watch will play - not by the abstract number of videos in each format. Some of your criticisms are valid - they're just minor and missing the point. We're never going to move past the PC if we have to drag along all the legacy. Most of that legacy exists to solve incidental issues and complexity than offering end users with real capabilities. Far from not being what I wanted to hear, the things you list are all in that category. You'll always be able to score points by saying 'but my PC does XYZ'. But the world in which we endlesskly drag along everything from the PC-era however crummy or hard to use isn't one I'd want to advocate for however much of an Apple hater I was.
