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.

Im genuinely upset.
Iİ own an onyx boox note air4c. I carry it with a cover put in a protective zipped case. Double protection. Seems bulky but the best way to save them. These are expensive and fragile devices.

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

HELP ME CHOOSE!
100% kobo. Its cheaper than the boox and in all honesty I think a better quality product. I had a boox note air 4c and it stopped charging (not a good look for all other product lines.) Kobo is repairable, boox is not. To get a black and white device that costs more than a color device is honestly s

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

Is it worth to get Na5c over Na4c?
Only for Android 15 is it worth it. Android 13 is from 2022 and 15 is from the end of 2024. In terms of OS support, you are guaranteed at least 2 additional years (Android 16 is just beginning to be implemented) so, for this alone, it is worth it. Also, let's not forget that BOOX only guarantees 3 y

Whoops
You are not alone! On day 3 owning new Air 4C I put the reader into bag, hang the bag on the chair not realizing the bag strap is longer than the chair. So bag ends up hanging but also partially on the floor. I move the chair so one of the legs goes over the bag. Not noticing that I sit on the chair

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.

Oh boy, I did a thing. After 24 hours of discovering the phone, I'm hooked!
I'd love to have an e-ink phone but the screens are so fragile (RIP Boox Note Air 4C...idk how your screen broke, but I'm still sad it happened). I'm going to pick up a TCL NxtPaper 70 Pro if they ever release here in the US as sort of a happy medium between usability and eye comfort.
