I went during lunch time to the FNAC store to have a look at this new device.
First thing : the people at FNAC didn't know they had it in stock

They knew nothing about it and even one of them kept believing I was talking about the Aura HD (and then why was I asking to see one in flesh as there was an Aura HD for demo)
So one of their people went down to fetch one in the backstore so that I could have a look. Impossible to manipulate it as it was not set (impossible to bypass the registration with the 2.9 firmware ?). But I could have it in hands : nice feeling for the back, the (very small) diamond pattern of the screen can be seen, but I don't think it could bother me, no glare that was a deal breaker in my point of view. Smaller than my Glo, a bit greyer when the light is off. I was fearing that it would feel as if the actual screen was behind a "glassed" frame but it doesn't has this feeling at all. It doesn't feel either like a tablet or a smartphone. For the time being, I was please with what I saw.
I'll have another look tomorrow or the next day (when the FNAC people will have found their ID and password to set it, as they where asking each other who had them

I wonder how they can advise anybody, about ereader buying, as they seem to know nothing about them :
I gave them tips about what was knew about this one, they just thought it was either the Kobo Aura HD, or a smallest Aura HD, it's just a pity, even if this store is a small one ! )
