I just got a Surface Book 2. I had a Surface Pro 3 during my first graduate studies and found it to be wonderful for reading and highlighting articles as well as typing up papers of my own (I wrote my whole Master's Thesis on it no problem) but it was getting a little old, the battery wasn't lasting as long and it was slowing down. So I upgraded for my second round of graduate studies. It's a beautiful device. Even better for typing, a slightly larger detachable screen (that's even lighter than my SP3) and better battery life. I think this was a wise (if large!) investment.
