In addition to launching the new $899 Surface Pro 4 with the Surface Pen stylus, Windows giant Microsoft has another highly-popular Apple product in its crosshair: the MacBook Air.
Billed as “the ultimate laptop,“ the Surface Book is another hybrid device from Microsoft. Featuring an accurate, responsive stylus, multi-touch support and a high-resolution 13.5-inch optically bonded screen that detaches easily from the keyboard, the new Surface Book promises to offer best of both worlds.
