>Ex: Many apps go to the browser, but the user might not remember which app sent them to the browser. They might have thought it was Twitter, when it was in fact the home screen. This is exactly what I like about the back button. Frequently I'll finish an article I was reading in the browser but not remember immediately what brought me there. (This might happen if I had to interrupt reading it for a moment to pocket my phone and use two hands.) I'll have a sense I'm supposed to do something with it, but what? Did someone text it to me? Was it in a Gchat? Email? "Well, that was a good article... why am I here, again?" I hit back, and find myself in an email with a link to the article. "Ah, yes, that's it! Joe emailed it to me." Now I can reply to Joe about it. Maybe this wouldn't be as helpful to others, but I like it because I'm quite forgetful.
