After watching this segment, this is my take away: Wall Street Journal's Walt Mossberg has an insightful comment about people don't want to carry iphone plus iPad plus laptop all the time, true. David Carr says how much it is a family computer, True. What is going to happen? People need to have multiple iPad. Leave one in the bag. Leave one in the living room. Leave on in the dining room. It is a "pick up and use" device. Expensive? Sure. But it works that way.
