Your opinion of too big maybe, Not others!
Galaxy Note II is where "smart phones" should be any smaller and it's a toy or novelty. You could say smaller than 4.5 inches is just a phone with some tablet features as well.
It's not as bad as people make it out to be, Easily fits in pocket!
I think you will see just how wrong you are as sales of larger than 4.5inch screens destroy all others in next year or two. It's probably already starting to happen.
Each to their own if you like using small phones then do so,But for me I won't have any phone with screen below 4.5inches, It's just stupid zooming in and out all the time just to try and be able to read the text on screen.
