That being said, I think the more time in apps vs mobile web might be a bit misleading. How many apps out there have webviews taking you to the web for various reasons? I can only imagine this time is counted as app time for the graph in the article, but it's really web time for all intents and purposes.
And frankly, I think that this is a much better user experience in a lot of ways. the facebook native app is much better than the web version is and even really could be (at least at this point). Much of what happens in that app though is clicking on websites to random articles around the web, and that is done in a webview inside the app. I like the app over the website, and i definitely don't want it to kick me out to safari while I'm in the app. This is a good ux, but I think it skews the data in this article. How many other apps have similar functionality?
All that being said, I strongly prefer the experience of native apps over the web, but I'm only interested in using the app if it's something I'm going to use all the time. If I need your site 1 time ever, I'm not wasting time downloading the app. If I use it every day, I absolutely would rather have an app. For everyone saying "Hell no I don't want your app", I suspect the above is actually true for a significant majority of people. 1 time use people don't want app. Repeated use people do want app.
