Fine. How about email though? Drives me crazy that I can't specify which app I want to use to send an email.

Oh, i wasn't disagreeing with OP, i was saying that even the "choice" you have for browsers is not exactly a choice.

It's not a choice of rendering and javscript engines, but it's still a choice of browser sync ecosystem.

I'm loosely locked in to Safari on Mac/iOS if I want my phone's default browser to sync its bookmarks to my computer, because my phone's default browser can't be anything but Safari.
