The experience probably varies quite significantly from person to person. I remember appreciating the decrease in size when I upgraded from my 4" Nexus S to a 3.5" iPhone 4S.

Facebook pioneer the idea of a side menu that could be swiped open with a gesture, and that technique should allow for easy one-finger usage on even the largest screens.
