One Handed Operation: How Big are your Hands

A popular theory justifying the size of the iPhone revolves around this theory that "Anything bigger than the iPhone is unusable with one hand". But I'm curious if that's actually true.



Grab your 3.5" iPhone and lets see how far your thumb reaches comfortably. Does your thumb reach the opposite bezel? The top bezel? Does it go far beyond the opposite bezel? Does it reach all the way to the earpiece? Are you missing a thumb? Im just curious if the whole "one-handed operation" is exaggerated or not.
