I have fairly small hands, but still prefer a larger phone. More content on the screen and space for battery.

HOWEVER, I’d take both. A small phone would be a good secondary device. I want something modern the size of my Samsung Galaxy Ace (GT-S5830i). The back also has a really nice texture.
Oh, yeah, it also has a headphone jack, MicroSD card slot and quickly swappable battery which I should probably replace because it seems it has slightly increased its capacity… volumetric capacity.

But I also prefer a bit more thickness so it doesn’t feel like a fragile, slippery sheet of glass (rugged phones are good for that).
