Interesting. I am from the USA. That does just go to show it is a regional thing. I would say the majority here would place more importance on battery life and portability. I see a larger screen as detriment to a devices portability which is why I rarely carry my iPad around with me unless I have my backpack. Plus some of the pants I own have tight pockets (i hate that) and it makes it a real pain to get my iPhone in and out, let alone a bigger phone. The extra screen real estate is not worth it, and if/when I would need it I usually have access to my iPad, Apple TV, and MacBook pro. In my mind the "bigger screen" wars ended with desktops (except maybe with TVs it is still thriving?)
Yeah it's a regional thing ...
