I have been investigating this line of ereaders for the past few weeks, as I have been considering updating my iPad—which, honestly, I really use 90% for reading books, and websites (newspapers, magazine sites, forums like this one, etc; and to a small degree, email). I really prefer my iMac for email and any kind of actual work with writing or documents. I only use my MacBook Pro when traveling, as I just find my 27” iMac screen (and a keyboard) so much better for everything when I need to work on multiple things (or applications). As you can imagine, I haven’t traveled in nearly 2 years now!
People claim that e-ink is so much easier on the eyes, but i really don’t have a problem reading on LCD screens all day, every day. Which I do and have done for 20++ years. 😀
What attracts me to e-ink is the transmissive screen tech and the (possibly) exceptional battery life. I say ‘possibly,’ because the battery life of an e-ink device seems heavily dependent upon functionality. So, reading doesn’t use a lot of battery…but anything else (such as one might do on an actual e-ink tablet with note-taking and other capabilities) requires specific software adaptations to maximize battery life.
I know I’m being long-winded here, and I hope I’m not too off-topic! I just jumped in to comment, since I have been torn between a replacement iPad Pro (initially I considered a Mini 6), or something running using e-ink. My current iPads are both slowly dying. I’ve managed to weaken the USBC connector on my iPad Pro 11 (2018) — it still charges, but I have to pay attention to make sure it connects properly. And the battery life has shortened a lot. My 2017/2018 iPad Pro 12.9 battery life has gotten really short…and it’s slow and looks and feels clunky. 😂 SO, I really need to replace at least one of them soon!
