But have you ever seen a family use a all in one pc device? Even though most of us find it easier to use a mouse/keyboard,I've sat and watched family members who bought one of those larger 21 inch all in one gateways sit at the desk, use the keyboard or mouse to open up their email, then flip over to a web page and start flicking their way through links by touching instead of using the scroll mouse.
When Intel's UWB wireless monitors hit mainstream I think we'll even see more of this - you might pick up that monitor off it's cradle and sit in the comfy easy chair across the room and use it as a giant 20 inch tablet. Not to mention artists who might lay it flat to draw on it. I think the next unsaid interim step for that will be the kinect for windows. Late last year Kinect they started talking with manufacturers about building kinect into monitors & tv's for Windows 10. We might see those designs by christmas or early next year. I don't want an xbox but I wouldn't mind having a kinect interface with the TV for accessing channels and such ala a tivo or roku interface.
