e-reader for university library books?
You could look into the Boox Air 4C and 5C. Make sure to look up reviews because Boox devices can have quirks and you cannot expect updates. In general I would recommend going with a 10 inch screen or larger for those types of books.

Something going on at Boox?
This is something they do, and it's pretty annoying, but they do make good equipment... They basically make enough for complete run of a version of a product and sell it out completely before they move to the next version of the product. I got my boox note air 4C, because I was trying to buy a note

Boox Air 4C or Tab Ultra C Pro?
Note Air 4C for sure! Improved Kaleido 3 screen, more current Android version, better writing experience. Durability has never been an issue for me and I have multiple Boox devices.

My Long Wait for the Boox Note Air 4C — and Why I’m Already Thinking of Ditching It
TBH, I have Note Air4c , and I have used many tech devices my whole life, and this is one pf those devices I would say is having good built quality and is premium. There is no creaking sound as OP mentioned. Might be their device is faulty or a fake one. I do not know. Also, I am someone who does no

I’m Reluctant to Say this but…
I’ll chime in on this. The Kindle is great for reading but the processor on the Note Air 4C makes the experience better for large PDFs. Boox has a dedicated specialized PDF reader which works great and allows annotations. With Boox you can install any of the e-reading apps you want so it’s overall a

How long-lasting are Boox devices?
They say that they'll provide firmware updates for all devices for at least 3 years. Devices will obviously keep working after that, but they won't necessarily receive updates or bug fixes beyond those 3 years. I plan to keep using my Air 4C for as long as possible after that, but we'll see how it h

E-Notes & E-Readers
I used the Note Air 4C for my first semester of grad school. It was great. Read my textbooks in PDF format and took notes in class. Boox Notes app is great. You can clip information here and there and it will show up in an index of sorts. You can index your notes and create a table of contents so yo

I have a boox note air 4c since it was released and I use it daily for several hours, my cat has walked on it at least twice and it works perfectly well so far! From what I see, there's just a lot of faulty boox e-readers out there and I got lucky

Broke PhD Student - Lots of Academic Articles
The heart wants what the heart wants...lol. I had a Boox Note Air 4C and used it extensively during the first semesters of mental health counseling master's. There are so many features that it can be overwhelming. The screen broke, so that's how I ended up with the eNote Pro. It has much of the same

Tablet Recommendation for Note taking
I purchased a used iPad Pro while in college. That was great. I had a professor who didn’t want us using laptops ( handwritten notes is supposed to be better for memory/ processing etc) so I got around it by using my iPad to record lectures and write notes. I have Audhd so it was especially helpful.
