Microsoft is doubling down on its Surface devices business, unveiling a new laptop Tuesday alongside an updated tablet. Even as Microsoft has positioned the Surface as a laptop replacement, it's making a separate Surface laptop model, the Surface Book. Microsoft says its for scientists, engineers and gamers who need a lot more performance than a tablet. And while the Surface Book is called a laptop, the screen is detachable so that it effectively becomes a tablet. The Surface Pro 4 tablet is faster and thinner than before, yet it comes with a slightly larger screen at 12.3 inches.
