yeah, I agree. actually I don't know if I'd agree on the "vast majority" part, but the question of "is client-side MVC The Future?" can get kind of silly and messianic, while the question of "is client-side MVC A Future?" is undoubtedly yes.

there's a lot you can do browser-side these days which would be insanely masochistic without client-side MVC, but that doesn't change the fact that lots of very useful apps run on the ordinary web pages model.
