The Surface Pro 3 seems an awesome device for students. Being able to read PDF textbooks, hand-write notes while using diagram/drawing tools, browse the internet, follow along with (and write on/annotate) lecture slides, word processing with a physical keyboard, writing on PDF practice exams, etc, all in a single device is extremely convenient.
I have been using the SP1 as a student for over a year now and love it. I print all PDF hand-outs to OneNote and annotate them with notes from class. Everything is indexed so I can search across 5 quarters worth of notes in an instant and access them from any device.
I'm in business school (don't hate :) ) so most of our content is in the form of HBS case studies and diagramming and drawing graphs/charts is pretty common.
I see a lot of people using Notability on iPads. If I could get a Wacom or NTrig active stylus on an iPad, that would be sweet, but alas, not possible.
I agree that a device which can do all these is an excellent choice for students. As an engineering student, I used all of the above versatility on my HP TX2510US, and dealt with the burns that the poor heat management gave me :-)
I haven't played with the SP3, but I'm sure there are a multitude of other options as well which are well-suited to student use.
