I’m also a grad student and i love love love it!! My reason for buying it were for note taking and annotating/reading all my required reading and it’s honestly the best investment I could’ve made. Many of my classmates have an iPad or similar tablet, and although that is also nice, I enjoy that it isn’t backlit (for the sake of my eyes). I also have adhd and it’s perfect for me to have everything in one place so I don’t loose anything, while not having the option to also other distracting apps. Obviously I don’t know your field of study, so maybe it’s not as functional for you as for me, but I would recommend it as a fellow grad student!
I just carry it around in my pencil case after loosing my first one…
