I agree, they are better and faster! But they're expensive, from an engineering-time point of view. I think that small teams with a new product would struggle to have solid native apps on ios, android, windows, osx and linux simultaneously.

I've also gotten a pretty bad taste in my mouth about some companies pushing a native app down my throat. TripAdvisor would only show me the first three reviews on a place if I was browsing via mobile, as a way to push me to download the app. And now that they're on my android they sent me a couple of spammy notifications before I disabled them. I wanted to treat TripAdvisor like a website, not like an app that has access to all phone.
