Start testing on a mid range Android device on 3G and tell me you still believe that.

On mobile it's not just the file transfer that takes time: it's the JavaScript parsing and execution (on a single core) that hurts too. iPhones are massively faster than Android (especially cheaper Androids) at this, so many developers don't realize how much performance cost there is for a growing majority of their users.

Given how many different versions there are of popular libraries I'm personally skeptical that CDNs give you much of a chance if the asset being preloaded from another site. I'd love to see real numbers on this though.

I build games where the player is supposed to play for hours. Am I wrong thinking that file size matters less for me? It adds 1% to the loading screen.

Yeah for games it's not much of an issue.

It becomes more of an issue if you are doing a "business" app, where there's a lot of moving between pages and a lot of eventual page refreshes.
