I wrestled with this for a while because I loved my Note 3...but once I was being honest with myself, I was really just waiting for the edge to show up on a bigger phone, Note or no Note.
I realized that part of the reason why is that every new phone I've gotten has also been a change in form factor. Every time! After loving my Note for a couple of years, the Note 5 didn't feel like buying a new phone. It felt like buying an OLD phone. Yeah yeah, performance, resolution, etc etc. I wanted a new SHAPE, and this shape just happens to be
a bunch of beautiful awesomeness
Couldn't have said it better. LOL
You know what didn't factor in? The S Pen. Never used it. Kept trying on a regular basis, kept finding, meh, I have no idea why I keep trying. But I loved it anyway. The other thing that didn't factor in -- the "edge" features. Maybe interesting, maybe not. But really, just like the Note, it's all the OTHER stuff: big, beautiful, shiny, and the same performance as the Note.
Once I was honest, the decision was made.
