Thanks.
BTW: Surface Pro is called the tablet that can replace your laptop. It’s primarily a tablet, but it has a skinny detachable keyboard.
The surface book is primarily used as a laptop where the screen can come off. But when you take the screen off it loses some of its power because the GPU (graphics card) is in the keyboard of the surface book. I’m not sure how battery life is in the surface book when in “tablet” mode.
