Take a closer look at Microsoft's two new Surfaces

Microsoft has just made its biggest device play in some time.

That play is in the form of a revamped Surface Book – the most powerful Microsoft has ever made – and a re-imagining of what a desktop can look like with the Surface Studio.

The Surface Book i7 was introduced with quite a fanfare by Microsoft’s devices chief Panos Panay, who made more than one reference to how the i7 is more powerful than Apple’s 13-inch MacBook Pro.
