The idea here though is that mobile devices will eventually become versatile enough to be used in these environments. My phone has an HDMI output and bluetooth capability, what, other than current usage patterns, is keeping Android/iOS from allowing you to plug in a monitor and hook up a keyboard to a phone? Hell, they are already doing it (albeit poorly): http://www.motorola.com/Consumers/US-EN/Consumer-Product-and...

The point is, I already carry around a phone in my pocket, and eventually, when I get into the office, I will hook it into my monitors/keyboard/mouse, and work away. The PC cannot keep up, and will eventually be replaced by this paradigm.
