Judging by the looks of it I think the demographic will be young men, i.e. GoPro type customers. And those that like to take photos whilst traveling.

I don't think it will be bought heavily by young girls/women that would be the typical selfie market that.

In saying that I think it will sell quite good. And I think that photo just makes it look larger than it actually is.
When the video is released the roam-e will look pretty cool I think.
