That's a tough one. I loved the 5.5" screen of the Note 2 while watching videos, playing games, or reading text. But once it came to being on the move, putting the thing in a pocket, trying to fit it in the cup holder of my car, whip it out and compose a one-handed text, etc....it became an inconvenience. I don't even think a bump from say, 4" to 4.3" would be noticeable unless it went entirely to width but then you start messing with one-handed ability. I personally think the best thing to do for the customer, if feasible, would be to offer two versions each release. The current size, and a larger version at 4.7" to 5" and let customers choose based upon need.
