Laptop Hybrid Microsoft's Surface Book i7 offers twice the graphics power

Were you worried that Microsoft would leave the Surface Book untouched during its Windows 10 event? You can set your mind at ease. Microsoft has unveiled the Surface Book i7, a refresh that focuses on pure power. The name is a giveaway as to the processor (surprise, there's a Core i7), but you also get twice the graphics performance -- the company added a second fan and otherwise redesigned the thermals to allow for faster GeForce GTX 965M video without cooking the inside. There's also a larger battery that promises up to 16 hours of battery life in laptop mode (no word on the tablet mode yet).

The catch: Aside from the absence of major external revisions (not that this is necessarily a bad thing), this will be one pricey piece of hardware. The Surface Book i7 will cost $2,399 when it ships on November 10th. Just another reminder that this is a flagship machine for people who want Microsoft's definitive take on mobile computing, and are willing to pay whatever it takes to get it.
