I'm not sure yet. I've only had the three for about a month. I love it! But, I have an upgrade waiting in the wings, so the plan was to sell this and pick up the 4. But, I'm not blown away by the launch. I'd like to see how real life use is.
I'm wondering about the battery with that screen, and I want to see how great the camera is in different lighting situations.
I also want to see if the edge is a gimmick or adds real functionality. I mean, Samy positioned the note for productivity, so I'm hoping they have a scenario in mind where the second screen is useful. Otherwise, why not have introduced it with the S5?
So, as of now, wait and see; and enjoy the hell out of this note 3. It really does still feel like a top tier device.
