While I know there is no absolute right or wrong answer here I was wondering what most of you think. I think we can all pretty much agree that 3.5" or 3.7" screens are too small. The real heat is in the 4.0" vs. 4.3" debate. I find 4.3" phones to be too physically large for daily handheld use. For me, 4.0" is the sweet spot.
