Can the Surface Book be used as drawing tablet while connected to ext. screen, mouse and keyboard?

I'm thinking about getting a Surface Book (coming from a MacBook Pro), and one huge thing that would sway me would be if I could use it with the screen attached "backwards", folded flat, as a drawing tablet, using it with an external keyboard and mouse for input, and an external screen for extra UI real-estate. (With Windows still in "PC mode", not "tablet mode"). So, basically, using the laptop itself as "just" a drawing tablet, as if it were a Wacom Cintiq.

Is this possible?

Thanks!

Yes it is :)

Oh, great! Have you used it that way? Does it seem practical?

I use it on my pro4, I have one note open while I copy and paste things from my 2nd screen onto one note, works like a charm

I have my SB connected to two external monitors, and I occasionally flip the screen around, and use the pen to do math assignments. I sometimes use OneNote, and sometimes Word, depending on what I'm doing. Word is great for homework because I can export to pdf easily with properly-sized pages, for submission.
