Unfortunately it is not only you. _A lot_ of my employer's customers complain about frontend performance and the fact that the UI is generally made with assumption of fairly large display (almost everyone in the company has got 27"+ monitor whilst our customers are often on 2-3 years old business-versions of Lenovo or something similar with 14 inch of screen and 8gb of RAM top).
And yes, that's right, who cares. People like you are minority (people on phones are majority), people in enterprise settings don't have a voice and choice, and economy drives everyone towards using web stacks.
Also I guess my expression wasn't exactly clear. What I'm trying to convey is that technical superiority doesn't matter and users don't care about technical superiority. They care that music plays right away when they tap "play". And it is way easier to deliver that experience using web stack than any kind of native stuff.
