Great, another 5.2 inch phone like everyone else.
Maybe one day people will re-discover the appeal of the candybar and slim-flip form factors, who knows.
Whether it's for functionality or for status, bigger is better for a lot of things. Phones were the odd duck because the screens were tiny back then.
And it matters too for portable screens: otherwise 5" palm pilots, extra-large tablets, or 19" laptops would have been the norm, don't you think?
