Yeah, I'm not sure I follow why Samsung is releasing an Edge variant of the Note -- just cause they can? I don't know. I guess they can't leave out the edge screen/features for the Note series since it's their other flagship. As long as there are two variants, I guess it's okay. For note taking (and general S Pen use), it would seem to me the flat screen would make the most sense.
We'll see. Looking forward to the keynote, too. Even if I don't have plans to own a Note, it's still exciting to see what Samsung does next. And it might point to features in the S8 in 2017.
