I don't think it's a product of screen size, I think it's more a product of what phone (form factor) you own/started with.

My first smartphone (late to the game) was a Motorola Droid Razr. It's a little smaller than the SIII, but being my first phone, I just became accustomed to the size.

I use friends' iPhones a lot and the first thing I notice (other than just one button) is how small it is. Those same friends struggle with the enormity of my device.

I think it's a similar context switch from Windows <==> OSX. I think people can grow to like either of them, but using one after years of using another makes it seem unwieldy.
