If one is considering the surface pro or the surface book, I'd recommend at least also considering whether an OEM two in one laptop might fit one's need. I bought the surface pro 3, and while I liked it, I returned it when the surface book was announced, because I wanted something more like a laptop. Finally I questioned whether I wanted a detachable screen at all; really I was looking for something with a digital pen and a screen that could be folded back while writing. I found Lenovo had something that fit this description (available only in Best Buy, and the pen had to be ordered separately), and have been fairly happy with it. The screen is slippery for writing on, it doesn't have the traction of the surface, but aside from that it's perfect for what I need. I'm thinking maybe a screen protector would help.
