I keep repeating this argument in different forums, but: if you every lived in China you would realize that the native app is the past and the future. Since governments can block websites, that means they can block your web apps too. When I came to China I completely lost access to Google Docs, Gmail, Facebook, etc. Relying on web apps is exactly like giving governments the right to uninstall applications on your computer.

Right now this is not a big deal in most countries. Right now. But as the web becomes increasingly balkanized (and I believe it will) and as countries become less democratic (always a possibility) the native app with local data will reassert its prominence in people's lives.
