Microsoft certainly hasn't pulled any punches today, announcing a whole host of new devices, Lumia phones, and even a Development Edition HoloLens. While we probably didn't see the HoloLens coming, the introduction of the Microsoft Band, the Surface Pro 4, and this Microsoft Surface Book is a natural evolution for the company's product line. Despite this expectation, it still doesn't change fact that the Surface Book still delivers a lot of new functionality and advances for the tablet hybrid, which also marks the first time Microsoft has ever built their own in-house laptop. As with the Surface, the Surface Book has a removable, 13.5-inch screen with 267PPI. The device itself is housed within a machined magnesium body, which means it is both lightweight and durable (even if it makes you think of the MacBook), including the use of a "dynamic fulcrum" that replaces the standard hinge with a flex-type motion. The Surface Book also upgrades a user's traditional interactive perspective with a larger, back-lit keyboard and a new Surface Stylus Pen. In terms of hardware, there are the latest Intel Core i5 and i7 processors inside along with Nvidia GeForce GPU with GDDR5 memory integrated within the two USB port-enabled dock. Or, as Microsoft would like to summarize the whole product release, "this is the fastest 13-inch laptop ever made anywhere on any planet." The Surface Book will go on sale October 26th with prices beginning at $1,499. Preorders will begin October 7th. Learn more here.
