HTML5 support for things like geolocation / camera usage is inconsistent across models and generally brittle. The upside is that mobile web is really low friction and allows for instant deployment, but there's functionality and no good management system like the home screen.

I've used the Quora web app occasionally. But if I had actually had a Quora app on my home screen, I'd use it far more frequently.

Web applications can be icons on your home screen (at least on the iPhone): just click (+) and "add to home screen". If the application is setup correctly, when spawned in this manner it will also appear without any browser chrome, allowing it to be a truly full screen application.
