The fact that it's a single-purpose (ish) device, and that it feels and works so much like real paper. It's like being able to carry an infinite number of infinitely long paper notebooks with you. I used to get through about one paper notebook a month, and couldn't find notes I'd taken 3+ months ago. Now everything I've ever noted is available with 5-30 seconds of searching and paging about. The fact that, if I've written a bunch of notes in the wrong place, I can cut and paste them elsewhere is something I use every day. Everything is so much more organised. Also, and it's definitely NOT designed as an e-reader, but if you convert your ebooks to fit the screen, it's approximately the size of a hardback book page, which I find miles more comfortable to read from than my Kindle.
