that's not the web's fault... that's the fault of most developers doing the web wrong, refusing to separate content from presentation.

If mobile users only need service-type apps, the web can provide that. Programmers just have to write the screens.

The Web is a dumb terminal. You fill in a form, press XMIT or the equivalent, and get the next screen. Just because someone decided that the content needs to be jammed in a 900px table cell doesn't mean the web can't do mobile too.

How does that follow? That's saying that the mobile clients don't implement everything, not that http isn't agnostic.
