> Imagine Flickr on a tablet. Swiping, pinching, tapping. All of which can be accomplished without going native. These are accessible by normal web pages using JavaScript.
> Try spending 30 minutes going through newsfeeds and photo albums without having the javascript go unresponsive. Facebook has native apps already, and they aren't any better. You can't find new messages, notifications not appearing properly are some of the problems I face. And you don't have to wait 30 minutes to have these problems. They appear before opening the app!
