As much as i have loved loved my note phones over the years, i don't care for the fold much.. i set up a friend of mine's and while it's a nice phone, i always said if i wasn't getting a note i would go to a smaller phone. The fold is basically 2 phones together side by side, i don't need it open to a tablet, i have one.
As far as the fold itself it's a badass device, i would have to put a case on it tho.
I got the flip 3 instead, because while it's still thick closed, it's a smaller footprint, about like a pack of smokes, so it carries a lot easier and is easier in the hand to me..
My opinion, yours may vary, but after 2 weeks i really enjoy the flip3, my friend is scared she is gonna drop her fold... so think about what works best for you.
