Rrreally? I was webdeveloper, and I got sick of the speed of HTML5 development and they way it was done. (not using XML by default is just inexcusable, for example) Also, HTML is general simply sucks or application-like development. It was meant for text, and for that it's fine. But doing easy layout, consistent GUI elements, easy GUI development and interacting with the rest of the platform, that is still a disaster. And no relief in sight.

And low-end devices running Firefox? Hm. Yeah I guess at some point in the future even low-end devices are capable enough, but that point isn't now.

I like Firefox (it's my primary browser, since Opera went Dark Side with Google) but Mozilla only makes a hammer, and declares everything else a nail.

A well. Even the N9 can run web apps thanks to Hydra, and so will Jolla. Even if Mozilla gains some traction with their platform, it will most likely run just fine on my devices
