Like you rightly stated in the previous para, I cannot disagree more with this statement.
eInk like passive displays are in a league of their own compared to active displays even if it is Apple who is making those.
It's fine if you strongly prefer one, but it's kind of weird to strongly disagree with recommending looking at another option.
Like I said, once upon a time I believed that it wasn't worth trying. On a whim I did, and it turns out it's great.
The point of my comment is to show what changed without prejudice, but apparently that's quite an inflammatory thing. I guess forgot about the "I'd replace every screen in my life with e-ink in a minute" cabal, which does tend to be pretty sure their opinions are The One True Way.
