As has been said… same phone, minimal improvements. Unless the display is truly that much more impressive I can't justifiably use my two year upgrade to purchase an incremental improvement. With the snapdragon 810 around the corner in 2015 people would just be kicking themselves getting this hardware. Samsung is so bent on beating apple to the punch they shot themselves in the foot by not joining the 64 bit game on this hardware revision. I'm going to wait for android L and all of the things that come with 64 bit goodness.
As cool as the note edge looks, it looks like an expensive, flashy gimmick that will serve no real purpose other than being a footnote in the history of smartphone creation.
That being said, I still love my s pen, and will reserve my final judgments until I have seen them hands on but, like the S5, my first impression is one of thorough disappointment. Go home, samsung. You're drunk.
