"I’m reminded of how Steve Jobs scoffed at focus group testing of the ipad, on the grounds that consumers couldn’t judge a new product with which they were unfamiliar. But imagine for a minute that there was a focus group and you were running it. How do you describe the device to the focus group? An in-between device that’s too big for your pocket but not nearly as powerful as a notebook? Consumers will say they don’t want it. A device that has many of the most useful features of both notebooks and smartphones, that fits into a purse or small briefcase but lets you watch movies? They’ll demand it."
