I remember Steve Jobs berating phablets as "the Hummer of phones"
and dissing 7-inch Android tablets as too small, and disparagingly saying users would need to "file down their fingers" to use them - without considering how much smaller Apple users' fingers would need to be to use 3.5-inch iPhones.
I also remember the viral, doctored image showing the reachability of phone screens which "proved" that 3.5 inches was the "ideal" phone size.
