i've had the iphone since the orginal, thats why i said iphone's rather than iPhone 4, the difference between each one has only really been a matter of millimetres, the android devices i have seen have either been longer, wider or thicker than the iPhones, or have just not felt comfortable when holding them compared to the iPhone. like i said, that is MY personal opinion and preference, so you cannot really question that.
That's why I pointed out that devices like the Samsung Galaxy S are actually smaller than the iPhone 3GS. Not in width or in height, but in thickness, meaning the overall bulk of the device is actually lower than the 3GS. So it's a bit of a fallacy to say you prefer the iPhone because it's smaller, when it is in fact bigger than some of the high end Android devices. I think you were maybe talking about one particular dimension, not the overall size of the device.
