I have to say I'm glad I passed on the Note Edge, as after having a chance to use it, I came away with doubts about it. That side screen really was somewhat awkward and in the way. It was kind of weird having the screen in portrait but the side in landscape. Then there's the issue of your thumb being on the screen. From there, I played with it a good bit, and tried to find how I'd potentially use it, but I couldn't find any really use for it beyond the novelty.
Conceptually, I like the attempt at something unique. However in actuality, I don't think it works out. It was so strange having a part of the screen sideways while the rest was portrait. Also, I found having additional home screen shortcuts in that bar, to be pointless and redundant.
