I'm a student (doing chemistry stuff) in the Netherlands using a surface pro 4 for my study (Molecular Life Science in Wageningen if you're interested), every day life and almost everything else.
I have nothing to complain about so far, but battery life (I'll get to that). My surface pro 4 (i7 8GB RAM, 256GB SSD) is an excellent device. I use onenote 2016 (because office 365 is free for students) for making notes and doing exercises, I barely use pen and paper due to windows ink options and I can quickly take pictures of lecture notes with the rear facing camera (not possible if you don't have a rear facing camera) when the rest of the class is trying to keep up with typing.
One problem with the surface pro: it's a tablet that can behave like a laptop and not a LAPtop. If you plan on using it a lot on your lap (like for example on the train or in the bus while travelling), I'd say it's not ideal.
Because I do so much with my surface pro, the battery life is sometimes a problem. You shouldn't have this issue with the new surface pro (5), because it has more battery life although I have never used that surface so my statement is based purely on the specs.
If you do a study like me, where you have to draw a lot (think about chemistry molecules or forces in physics) I can recommend the surface pro 4 (or 5). If you have to do a lot of presentations, I can also recommend the surface pro 4 (or 5), since you can hold the tablet in your hand with a pencil drawing during the presentation.
But if you do not have to draw much or do many presentations and are just looking for something to run office and do regular web browsing, I'd say the surface pro is too expensive.
It's a device that can do a lot, but if you are not planning on using it's many extra features I'd say it's just a waste of money. In the last case, I would recommend buying something a lot cheaper.
