It's a little ironic for such news to end up here, because I'm pretty sure Opera (mobile) is the only one of the major browsers still supporting text reflow, which is why I use it for reading HN which doesn't have an official mobile site version.
for whatever reason, they all removed it. Android stock had text reflow (and inverted color night reading). then on 2.3.3, gone. now they don't even have a stock browser. they ship with chrome, installed as a system app.
firefox started with awesome text reflow. then i think on fenec v16 they screwed up everything when moving to the Reader feature just to clone safari, safari for f* sake...
I think I should do a video capture how nicely pretty much any site works in this browser. Unless the text is burned into an image, you can pretty much read it all without horizontal scrolling.
This feature is badly needed in Mobile Safari, Firefox and Chrome.
I really hope Opera can continue to support this amazing browser.
