I got similar feelings as the OP though. It's not just about notifications popping up or having a browser at hand. I feel the epaper display puts me in a different frame of mind. A "Not sitting at the computer" state, in which I think differently. So I always wondered if writing on an epaper display would not feel entirely different than looking at an empty page in a word processor. I certainly feel the difference when reading a book an my ereader vs. my phone/tablet.
