It is ludicrous to think I would write here that I find the Aura One not as crisp as the H2O just in order to deter potential buyers. I find the idea insulting.
I was just stating my first impression, with both device next to each other. You may or may not have another opinion, this is what forums are for. After hours of reading, I can only reiterate that, IMO :
1. My One is not as crisp as my H2O. Not by much, but it is noticeable, at least BY ME, which is the most important, as I happen to be, oh surprise, the user of this particular unit (gosh, to think I even have to explain that,,,,

)
2. It is slow in turning pages
3. The lighting concept is great
4. But I see colour blurbs when the brightness is around 10% and the natural colour is on. Especially a redder cone in the bottom left. ON MY DEVICE.
5. The haptic is very good. It is a pity to use a cover.
6. Highlighting is subpar.
Regarding point 1, I know I am not the only one, a reviewer wrote the same elsewhere, but I don't remember who and where as I saw that a week ago. Obviously, since I do have what is called a life, I won't spend hours looking for it. I just happen to have the same opinion.
Come on, tear my post to pieces....
