I just got my 700 a few days back.
Honestly, I am disappointed with it.
First of all, the words are not clear, slightly foggy and that is a real turn off.
I mean so much for the e-paper and how it reduce eye strains when the display is not even clear

It does get better when I use it with a bright reading lamp, not something I do very often.
Secondly, the glare. Damn, I can even see features of my face, when lights bounces off my face, i.e. bright patches of the left side of my cheek bone and nose, when the lamp is on my left side.
I will just have to get used to it!
And, I still choose to think the technology is not mature enough. It feels like a gimmick/toy to me |:
