Yeah, but the users of the dominant smartphone demands native apps, because that's what they're used to. No matter how fancy you make your webapp, it's gonna be laggy over a slow connection, and the users will move on to some similar service that offers a native app.
Some foodstuffs company whose name I've forgotten tried to introduce yellow ketchup in my area a couple of years ago, but they failed pretty badly. I bought a bottle, and while it tasted just like the the red stuff, it just didn't look right. My 5 year old niece just flat out refused to eat it.
To be honest, I'm more fed up with the constant handwringing about them over here. I've never even heard of them outside of here, and I've never seen them in my search results.
