Anyone have a 4.7"+ (S3, One X, Optimus G, etc) who can share their assessment of Size vs Usability?
With all that said, I will say that I have to imagine the size would make things less than optimal for some folks, but I don't think it's a matter of device size so much as the way most software behaves.
I'd like to see more apps consider a bit more than simply extending their basic portrait / landscape layouts.
I'm disappointed I haven't seen more things along the lines of the old Xoom radial menu [1] or the split and / or off-center controls you can find in some third-party keyboards.
