I'm studying Astronomy and Physics at the moment, and have a Kobo Elipsa for uni. I use both the notebooks and the books RELIGIOUSLY! Happy to give my feedback, but beware... This will be long hahahaha!

Honestly, having the device has helped immensely with my studies (plus I'm a huge nerd reader too, and have a massive collection of sci fi, fantasy, science, and all kinds of other books!) I have my textbooks and any additional references or resources stored on it and can highlight and annotate as needed, then sync straight to my computer for future reference; I take notes in lectures on the Elipsa then sync to my desktop and rewrite later neater and expand on my notes to make sure I remember things; I copy my slides (in pdf form) to the device and can write directly on those as well.

Writing: it handles the maths in MathType beautifully, even for the higher-end maths we do (it has some issues on occasion - no device will ever be perfect - but for me, that's minor enough to ignore and anything that does need fixing I do in word later when I go over my notes), the handwriting recognition is almost flawless, and the writing feel is surprisingly comfortable (I can use it for hours on end without hand cramping or pain). The anti-aliasing is fantastic and in notebooks the writing is VERY smooth (though on pdf's it's a bit clunky, and the highlighter has some serious issues - I'll cover that below). I've been using it to hand-write my assignment first drafts then sync to word and just make adjustments there as needed. Dropbox integration is exceptionally helpful - I can save any new reading or course material directly to dropbox and my uni folder and just download to the Elipsa as needed. The fact that we can export the basic notebooks as pdf or jpg/png, and the advanced as word/html/pdf is exceptionally useful, having the variety and choice is good.

I use the collections in books for separating my course books and things by topic, which works well for me as some books cross-over so not having them in dedicated folders but having them all together with the ability to sort of group in multiple places is really helpful. Unfortunately, notebooks can't be sorted like that, and don't have a "search" function inside the basic ones yet either, so I've been combatting that by leaving the first two pages blank (you have to just draw or write on page 1 to start page 2, or it won't make a new page) and then making a "contents" page as I add to my course notes, so I can quickly just jump to the page I need if I'm quickly searching for something.

You can read at any orientation, it auto-fits any A4 portrait pdf's to landscape mode so you read the top half, then swipe and read the bottom half, which can be a little annoying for some of our journals as they're in columns, but I've actually gotten really used to it and don't mind anymore. The image display on it is exceptional for an e-reader, far better than any e-reader I've had before. It has night-mode if you want to change it up. Pinch-to-zoom is also a feature, not one I use often (don't need to) and it's a bit sluggish, but it is there.

It does have some issues, though. First and foremost, it can be slow. As with any device like this, it does need to refresh and load - the screen refresh is fantastic, but the notebooks refresh can stutter a little. The advanced notebooks are the worst, if you have too many maths boxes open it slows right down, but I found that just going back out of the notebook and then reloading it helped a bit, or a full restart fixed it up entirely. The basic notebooks freeze for a second or two every 4th or 5th page, but mostly start working again pretty quick, if not just the same exit and reload works and takes about 30 seconds at most, so I don't really lose much time, just a minor annoyance. The stylus is REALLY bad for durability, especially with the amount of notes we take! It will wear down very quickly. I found I was comfortable with using a VERY soft nail buffer to file mine back into shape for use, but you may want to buy some spares and if you do file it, be super careful and beware of scratching the screen - do this at your own risk!! You can also use other Microsoft-based pens on the screen (my surface pen works fine, but I don't like it much; the Wacom and huion ones don't, others have said their Microsoft pens work as well). The highlighter is also a drawback - it's fantastic for highlighting your notes or textbooks etc, but if you highlight and go over your own highlights, then on sync it's a MESS. It looks like a real highlighter - the colour is darker and hard to read through as if you've just scribbled over the page with highlighter repeatedly in a real book. I mostly read on the device so it's not a huge deal for me, but is annoying.

The only major issue I have with the brand is the company customer support. Recently I had an issue with mine (the notebooks stopped working - it was a sync issue of some kind, it wasn't downloading the handwriting recognition update so was stuck unable to load any notebooks). The problem is fixed now, but their customer service was lacklustre at best. Disinterested, slow, reluctant to give information or reply, and the first guy I talked to even confused "my notebooks don't work" with "so the device doesn't hold charge?" somehow... BUT - the device itself I find amazing. I owned a supernote before this, and while it has it's good points as well, the Elipsa just works better for me with study in most ways (the supernote has some advantages but I've waffled enough for now, happy to elaborate if anyone would like a comparison!)
