What about letting the user know that the width is being fit to view and show the progress? Then there are no mysterious delays while loading pages. And the user would not forget it's on. Or is it the case that fit width to view is done while loading? I get the feeling it's not based on my default use of fit width to view always on and the behavior of the browser.

I do have some faith that the Fremantle browser will not remove functionality.
