Oh boy. The endless HTML5 vs Flash discussion has come here as well...

HTML5 is markup, people, nothing more.

What perhaps is intended is support for a feature complete web stack: HTML, CSS, DOM, ECMAScript and the auxiliary technologies like XHR, SVG, audio/video codecs, geolocation, web workers...

Add to that JavaScript with JIT or tracing and GPU accelerated Video, SVG, canvas, etc and a few other performance boosting rewrites of the rendering engine (e.g. retained layers in Gecko) and yes, new kinds of web applications are made possible.

But it is not all HTML5.

Some of these technologies have a new number after them: HTML5, CSS 3, ECMAScripth 5th edition, DOM 3, XHR2, etc. But it's only a number, people, nothing more. Exactly what features from the specs do you miss in Fennec or MicroB, and why? That's a far more productive discussion.

Oh yes. Nokia ditch MicroB and support Fennec or add SVG to MicroB!

I really, really want SVG in my browser, because I use that a lot in my teaching.
