If you don't mind would you elaborate on what type of content you meant when you said: "centralized authority produces the content for passive users to consume". When I think of content the first thing that comes to mind is stuff like image editing (Photoshop, LR3,Aperture etc) and video editing because those are two realms I spend my free time in. I didn't get what you meant by your statement so that's why I asked.

And just to be clear I do believe that tablets are aimed at content consumption and not so much content creation, and I believe that to be a good thing. Why? Well people don't need a $2000 laptop to surf the web and check email.
