Also, they envisioned tablets to be used mostly in landscape. That's why we got everything on a single bar at the bottom. The basic concept behind Fragments was pretty much the same as WebOS' Enyo framework. I recall one of the big Enyo demo moments was when a browser window was resized, and the email app ui went from multiple columns to a single column, and back, without missing a beat. Then again i wonder if Android was partially designed, before Fragments, to rekindle the experience of using Apple's Newton tablet. This in that one app would extend the functionality of another app in a virtually seamless manner via intents. But as best i can tell, Android left too much of the plumbing in the hands of the app devs. Thus for every app that handled cross-app intents properly, you got 100+ that would jump back through the in-app activity history rather than roll back the intent chain. And with fragments you got a in-app way to do the activity history backtracking, while still having the intent focused back button of the Android UI.
