For those who will be sharing their tablets with children, the new Nook tablets will have user profiles so a parent can customize what type of content they want their children to access without having to create a separate B&N user account for them. That sounds like a huge plus to me. If they sold them up here in Canada, I'd be tempted.
I know that Nook targets its tablets to women, and I think that's why they chose a design with a bevel. My current 7" tablet has glass all the way across and it's hard for me to hold it. I hate having to hold the glass frame, so try to hold it in my palm which is very uncomfortable because it's just a little too big for my hand. (I stopped using my cover because I hated the extra bulk.) I think that's why the Nooks have the beveled edge - so that women can hold the device more comfortably. (The new Kobo Arcs have a beveled edge as well, which IMHO is a huge plus. That, along with the better features over the Vox, is a huge selling point for me.)
