Updated Surface Book
Earlier in the week, Microsoft confirmed a new Surface Book. The device was a little lost in major announcements like Windows 10 Creators Update and the Surface Studio all-in-one. The laptop is not a Surface Book 2, but is instead a re-tooled Surface Book. https://www.youtube.com/watch?v=A1OsmndtIrY Using the Intel i7 processor, the company got much more power out of the Surface Book and redesigned the laptop from the inside out. The updated Surface Book has 2x more graphics capability that any current model on the market. This means the performance is doubled and trebled compared to the best MacBook Pro 13.
