The screen is beautiful (a bit gray, but the black is really black so the contrast is still good), the device is thin and reasonably light, I only have to charge it once a week or so, and there are absolutely no distractions. I have even rediscovered the visceral pleasantness of writing by hand.
I especially like that it's *not* running Android (which I dislike more with each release). The biggest drawbacks, to me, are the fragile pen nibs and the inability to just SCP a PDF or EPUB to the device and have it work (their sync software works but isn't great).
