Microsoft has unveiled the Surface Pro 2, a new version of its flagship 10.6-inch Windows tablet. Though little has been changed externally on the updated device, Microsoft says that what’s inside has changed quite a bit. “We improved the performance on this product by 20 percent,” says Panos Panay, Microsoft’s VP of Surface. “If you thought it was fast before, it is lightning fast now.” Panay says that the tablet is now faster than 95 percent of laptops and that its graphics performance has increased by 50 percent. The updated tablet includes a Haswell processor, and Panay says that it’ll see a 75 percent improvement in battery life over its predecessor. The Surface Pro 2 is also trying to address one of the biggest complaints many had with the original tablet: that its built-in kickstand was difficult to use when propped on your lap. The new tablet’s kickstand has a second position that can prop the tablet up at a 55 degree angle.
