I got the 32 gb jawnsif you're gonna spend an extra $100 on a Galaxy S6 you're better off getting the normal one and doubling your internal storage capacity than getting the Edge one. The Note 4 Edge from how I understand it is extra pixels. the Galaxy S6 Edge is a curved regular screen around the edges so that edge part is part of the normal screen real estate.
I was thinking is more space but I don't need it...I kept my galaxy 4 as well
