I hear that it’s quite possible to jailbreak your kindle these days, and that sounds super cool.
But a lot of e-Readers tend to be quite expensive. Why would you purchase an e-Reader if you already have your phone? Even if you didn’t, your average phone is still gonna be cheaper than an e-Reader. Depending on the phone you’ll get, it’s also more durable and portable, probably even waterproof. Phones also tend to have more storage than ereaders. They even come with color. (I know color e-Readers exist, but they’re even MORE expensive, and they also come with their own issues that black-n-white e-Readers don’t have.)
Yeah, eReaders have more battery life than phones, and they’re also easier on the eyes. But overall, why buy an e-Reader to jailbreak if you already have a phone?
Less distraction, easier on the eyes, single-purpose and immediately jumps into your current book at your current spot.
I carry an XTEINK X3 with me at work so even the elevator ride can get me through a paragraph or two of whatever I’m reading. They go on sale often and both the X3 and X4 are under $100 at full price. You need to sideload your own EPUB files, but that’s never bothered me.

I’ve thought about picking up something like this, but e-ink displays tend to be fairly sensitive to pressure. They can get damaged (or even outright punctured) fairly easily. AFAIK it’s an issue with the way the e-ink displays are physically constructed, so it’s not something that can be engineered away with harder glass or a more durable frame. That’s a large part of why lots of the big companies also sell folding/flipping screen covers for their devices, as the added cushioning and rigidity helps prevent damage. So I tend to be hesitant to attach it to my phone, which tends to get beat up throughout the day.
To be completely honest, the magnets aren’t really strong enough to make me feel safe keeping it on my phone anyway. I just carry it naked with a screen protector, but there is a magnetic folding cover available too. It’s small enough and light enough that it actually probably takes a lot less damage from a fall than a phone that weighs 3x as much.
