I've said this before but I might as well post it again. I'm not thrilled with the length of the 8+ but I want the battery and screen real estate.
I think the dimensions of the Note 5 are optimum. (But that's about the only thing I like in this model. However, that's a different story.)
Anyway, when I went to a well padded, luxuriant leather folio/wallet case I found that the hard, unyielding edges of the S8 were no longer uncomfortable and a problem. The device felt smaller and more natural in my hand. That's my story and I'm sticking to it.
