It creeps up very quickly once you start installing site-wrapper apps. I consciously try to avoid those, but even a quick audit of my apps shows I have at least a few:

- Youtube

- Hacker News

- Reddit

- XDA-Developers

- Amazon

- My banking app

Pretty much all of those could just be a tab in my browser, but the convenience of properly-formatted text, easy searching, replying, etc pulls one towards the native app.
