And that would distinguish it from other operating systems in what ways?<p>Users of other operating systems are often not doing much more in their daily activities, and recent OS updates tend to support that more and more (OS X&#x27;s notifications, Windows start screen and metro apps etc.)<p>Apart from that, what does centering on messaging&#x2F;browsing take away from e.g. word processing or other office uses? Or how is multiplexing browser views inherently different from multiplexing terminal windows?<p>I&#x27;m not saying that I&#x27;m particularly fond of the way Android does things, but I don&#x27;t think its focus is to blame for that.
