Consider also batterie life and how it's affected by load cycle numbers: ablets get charged one every second day and e-ink devices once a month. Consider also technologie obsolecsence: estimate the times it will take in 10 years for your devices to open a book, change pages, mark highlights. I hardly open a pdf now on my iPad mini and my e-ink device from the same period seems to do the same operation at lighting speed.

I've never owned an E-Ink device, and didn't know they outlived tablets by such a wide margin. That's a sizable plus in the E-Ink column.

I mean there's no real innovation that will make your device anywhere near obsolete in a few years. My Paperwhite from 2015 is pretty identical to ones sold now, and unlike with phones and tablets, software support is still there. So unless you break it, it's probably gonna outlive your phone/tablet/laptop. Mine for sure did.

Yes, you're right if you're looking at update time of the display, which I have. There's pretty much no improvement. That's due to the physics of pigment particles. I don't see a way for them to improve that. They have improved contrast ratios. The whites of their carter displays are much better than the previous gen pearl and vizplex before that.
