Liking it so far. The brightness sensor seems a little over sensitive -- sitting near a window (3 or 4 feet way) and it seems to want to visibly go up and down as a bit of cloud goes by. Didn't really think I'd use that anyway. The natural light is a little different to what I expected. It definitely changes the tone but much more subdued than some of the pictures would suggest if you are in a bright room. It really does get red if it's in low light. I think I like it.
Size is great and it feels as light and better balanced than my H2O. I used to read one handed on my H2O and it's maybe a little harder on the Aura One because my thumb always was against the device with the H2O (just tipped edge down to change pages). With the One since I need thumb off the device to tap and the slightly bigger size it's harder to keep it from flopping around a bit. That might change as I adapt to it.
Responsiveness seems quite good and that's coming from someone who typically hates capacitive touch. I normally tap and this works well. When I just tried swiping it wasn't quite as good, but that might just be because I don't normally swipe.
Lighting is very even. If there is light coming from side (i.e. window) it can cast a small shadow from edge of the device down into the screen, other than that no particular shadow. At the bottom of the screen there can be a little bit of smudging from the lights, but barely noticable and may depend on brightness/natural light settings as I really can't see it now but I know I did before.
Power button takes some getting used to since you almost need to squeeze the screen to use it rather than the flick with the old.
Overall size difference feels like when I went from 6" to 6.8". Boy is it ever nice. The H2O looks sooooo small now. Funny how 24 hours ago it was a great reader and now it's just meh
