According to the website it's in the hands of some of the users. But then again people who wants to sell E-readers/tablets are known for a bit of "white" lies...
The Edge is useless, I think. It hasn't got enough juice to last a full school day, and that's one of the absolute necessities.
As for the Adam I'm not a reviewer, I have nothing to add to what pepole have posted around the web. But I can say that I have the PQ version, and except for the hysterically bad matte screen protector that came with it (waiting for something better) I have no problems with it at all. It's a nice unit in all respects, but I am on EdenX alternative firmware, not the original. I didn't really like that Eden launcher and the leaf system. But that's just a bit of personal preference.
Anyway after the last few updates to the firmware this is a very stable unit.
