On: An entire Mobile OS built using HTML, CSS and JS -...

Any serious candidate for an operating system is going to be complex. Personally I'm a little dismayed at current efforts to turn the browser into yet another cross-platform utopia. Some things will always be better native and pushing all this junk into the web browser just gets in the way of making basic things like a sane layout model that much more difficult.

Then just stick with the DOM and XHR APIs. Those alone have been consistently crushing most desktop applications since ~2003.

Wow. Can you clarify? Are you saying something like Google docs is crushing Microsoft Office? What DOM/XHR app is crushing photoshop?

I think there is a new class of "apps" that are emerging as web based, but they are creating a new segment as opposed to crushing an existing one.

First, JS & HTML are much more popular than Windows APIs. Second, I think johnrob meant that the DOM is more sane than most "desktop" APIs for laying out apps, not desktop publishing layouts.
