To start off, the new Surface Book improves battery life by 30% and can now, according to Microsoft, last up to 16 hours on normal usage. As the name suggests, it features the latest generation core i7 processor and doubles the graphics performance. Theoretically, it is three times faster than the highest end 13-inch MacBook Pro but we’ll discuss that after the Apple MacBook event. For keeping things cool, Microsoft says they’ve reengineered the cooling system and the latest Surface Book utilizes a more efficient thermal system. The company hasn’t revealed any other details such as storage availability or the amount of RAM. https://www.youtube.com/watch?v=A1OsmndtIrY Other than that, the rest of the Surface Book is entirely identical to what they unveiled last year – a hybrid ultrabook with a detachable display and a bundled stylus. It comes with a 13.5” PixelSense™ Display, backlit keyboard, glass trackpad, and obviously, runs on Windows 10. Surface Book i7 will be available for pre-order starting from today itself for a whopping $2,399 and shipping will commence sometime in November. Microsoft is primarily aiming advanced users who mostly work with resource demanding professional tools such as Photoshop or video editing and also, gamers who need something portable for casual gaming sessions. Along with the new Surface Book, Microsoft also launched a revamped version of their legacy Paint app as a part of their free upcoming Creators update. The updated application majorly aims to simplify the process of creating 3D models and digital images. You can read more about it here.
