Samsung's Big Bet on a Portable Screen That Few May Actually Want

Samsung just launched a portable 27-inch touchscreen display with three hours of battery life. It's a risky move. The company is betting that people want a large, battery-powered monitor for everyday use—a product category that barely exists today. Samsung faced the same gamble in 2011 with the Galaxy Note, but that succeeded because it solved a real gap between phones and tablets. Here, existing laptops and portable monitors may already do what customers need.
