The Microsoft Surface Book is a laptop turned tablet that is beautifully designed. It looks more like Microsoft's aim was to create a device that could do everything all in a small little chassis you could carry around.
It is an impressive machine, all round, but the pen dropping gets annoying eventually and makes it very easy to misplace.

Pros
Pro Great for hand drawing
The Book's multitouch support increases the possible range of motion and detail precision, which is something much appreciated for artistic work. The screen responds to 1024 pressure levels and is very responsive to the pen input. You draw on the screen and you actually get to see what you are drawing.
Pro Stable and comfortable to handle
The Book can be tilted at different angles and not lose stability, because of the curved edge of the detachable keyboard. This edge also proves to be quite handy when walking around or basically drawing without a desk to place your device on. It kind of gives the same feeling you have when holding the curled up pages of a book, thus making the experience that much more natural and comfortable.
Pro Great screen quality
The Surface Book's display is one of the best out there. The 13.5" screen gives you enough space to work on your sketches as you please. Having 3000:2000 pixels, nobody can complain about seeing pixelation on this device. This 3:2 pixel ratio really makes all the small details of the picture clearly visible, almost as you where looking at an analog image.
Pro Can be used on the go
The Surface Pro is, of course, a portable device, and therefore packs a battery capable of sustaining it up to 12 hours, with an extra battery boost included in its clipboard. This makes it all the more suitable for drawing and editing on the go, unlike some of its competitors that require a fixed power source.
Cons
Con Lacks hot keys
For someone that is used to a Cintiq and its EasyKey functionality, the Surface Book may be a disappointment, as shortcuts aren't available and users may have to use the keyboard more than they were expecting. However, it is possible to purchase the Wacom remote and configure it to be used with the Surface Book. Unfortunately, this will cost an extra $100, which is annoying considering Book's already high price.
Con The Pen detaches in your bag
The Book's pen is attached magnetically to the right side of the display. This feels secure when you have it resting on a surface, but when you place it in a backpack, the pen is bound to get detached and get mixed with all the other objects. This is a very annoying design choice, as users have to constantly worry about to loosing or misplacing the pen.
