At first I thought it was pretty interesting. The more I looked and read about it the less it appealed to me. I wouldn't call it a Pyra competitor, although there is some feature overlap.
Problems for me are that the Pyra is already pushing the limits of what I feel ids an acceptable size, and this thing sounds like it is larger. While skimming the article I linked I saw that the battery capacity seems unlikely to do it for me with what it is supposed to be packing (didn't it say two CPUs?). I am not a fan of those OSs, and I am trying to get away from using them at all. I suppose that may not be an issue if this will work with something I am more comfortable with. I prefer a clamshell, but that is pretty minor. A greater concern, especially since it isn't a clamshell, ifs being able to easily repair it myself. That serves a few purposes for me: It saves me money if I break something, sometimes I like to poke around in the guys for no good reason, I don't contribute as much to waste, and it is more responsible on my part (and that of the manufacturer, which is why I am also interested in the Pyra and Fairphone, and part of why I had my eye on Project Ara).
I think the 3D is interesting, but just like the cameras, I would probably never use it. I didn't look closely at the keyboard, but that is a positive, and it might be more comfortable to type on than the Pyra. x86 could be useful.
Overall, I like some of what they are trying to do, but this seems more targeted toward average consumers than it is to me, and I don't think it will catch on in that market. I think I would rather stick with a decent laptop and an older mobile phone of some sort.
