On Tuesday, Microsoft exec Panos Panay unveiled the Surface Pro 3, calling it a potential successor for laptop PCs. The device is not only lighter and thinner than previous versions of Surface tablet computers, but it is also larger. While previous versions measure at 10.6-inches diagonally, the Pro 3 screen measures 12-inches. Along with other Surface tablets, the Pro 3 is powered by Intel chips. Rather than comparing the tablet to others on the market, Panay discussed Apple’s MacBook Air as a competitor.
