My wife recently bought an S7 Edge. I haven't spent a lot of time on it, but it seems to be a well-designed device. It's a good bit smaller than my Note 4 and yet the screen feels almost the same size (it's smaller, for sure, but .2" is not THAT noticeable. It's a gorgeous phone, feels great in the hand, and what little I have done on it has been very snappy and responsive. The camera (for lower-light situations) is top notch. In daylight, my Note 4 can still take better pictures, but for 90% of actual picture taking the S7 Edge camera trounces it.
In my case, I carry a spare battery all the time and use it on occasion, and I also use S-Pen frequently. I couldn't stand to lose both of those features, no matter how shiny the phone is. I'm waiting for the Note 6 in hopes that they might reattach a few things they castrated off the Note line with the 5.
However, the battery life on the S7 Edge is really good, according to my wife, and it does look like a solid performer if you don't use your S-Pen at all.
