Honestly, if you have a word-editing program that you like and you're only going to be taking notes/web-browsing/light research, pretty much
anything will do. Your primary concerns are the keyboard, battery life, and whether or not Android has the apps you want. Unless you're in a field of study where you'd need to spend a considerable amount of time drawing diagrams or equations, you really don't need the S-Pen or anything like that. If you want something that records hand-written notes, you can always sideload APK's (like the ASUS Supernote).
I'm an undergrad working on a research paper, and I'm actually using my Nexus 7 just fine, with a keyboard case. My hands are small enough that working on a miniature keyboard doesn't bother me (I've gotten the hang of it, but I wouldn't recommend it for fast-paced lectures), and I really like the size because I literally have it with me at all times anyway. I just head to the library with my N7 and a portable book stand, and I'm set. Freshman year before tablets became mainstream, I had my old clunky 17" laptop with a weak battery life and an enormous charger. I can only imagine what you used for freshman undergrad
.
If you
absolutely need the full functionality of MS Office, the Surface RT (which comes pre-loaded with it) is a worthwhile investment. But then again, you don't have the Play store's app market. If apps like Kingsoft/OfficeSuite/Evernote/Supernote/etc are totally fine for your needs, you could get something as cheap as the Tab 2 10.1" ($350 16GB w/microSD, for which you can buy
this neat Logitech keyboard case). Another question is whether or not you'd need a statistical package--I haven't found any worthwhile apps for Android, and I doubt the Windows app market would have anything better; in that case you could look into tablets with a full x86 OS like Windows 7/8 (alternatively, root/install Ubuntu).
The other question is the keyboard. Would you be fine toting around
a separate bluetooth keyboard, or would you want an eloquent keyboard/case combo? Since then N10 hasn't even been released, there won't be many options readily available. Keep in mind that with slim touch keyboards (like the advertised Surface one) you'd sacrifice considerable typing efficiency.
My word of advice is, you might end up using your tablet wayy more often than you expected, and for far more purposes than you intended. I got my N7 just for kicks as my first tablet. I meant to use it just for occasional, light note-taking--in case I didn't need to lug around my laptop--and media consumption (e-reading, Netlfix, etc). With a plethora of productivity apps, it's helped me stay organized; with a $10 navigation app, I now retired my old GPS; due to its portability, I replaced my iPod; I use it to download/read research articles; etc. So you might as well get the best device you can, if you plan on using it a long time. Good luck!
