macbook owner looking for surface advice

Hey, I am currently a student who is using a retina macbook pro 15" 8gb ram 512 HD. I currently have half the hard drive dedicated to bootcamp.

Anyways, I am curious about getting a surface 2 or surface pro 2. I am considering two options:

One, sell my macbook pro and buy a surface pro 2 and docking station. I really like the digital ink concept for notes.

or two, turn my macbook pro into a dedicated desktop and buy a surface 2 and use a capacitive pen.

The draw back being I am not sure how much I can get if i sell my macbook and what if i do not like the surface for school? Also, how much better is digital ink, is it worth it?

Thoughts, ideas, advice?

Thanks!
