Even after announcing the Surface Pro 4 being a tablet that works like a laptop, Microsoft also announced the Surface Book a brand new ultrabook with a 13.5-inch screen. It is presented as the most powerful 13-inch laptop around, with the latest Intel processor and Nvidia discrete GPU, which gives it twice the performance of rivals like the Macbook Pro.
Its screen supports 267 PPI, and they system promises 12 hours of battery life. The laptop is designed specifically for power users, and can run games like Gigantic and Gears of War.
But it looks like Microsoft is being cheeky with this one. The Surface Book is actually the Surface Pro 4 with a base that boosts its capabilities. The screen, which is a Surface Pro 4, can be detached from the keyboard for alternate viewing modes. The solid keyboard base houses the Nvidia descrete GPU. The base features a backlit keyboard, two USB 3.0 ports, and a full sized SD card.
