When I first chose a big phone it was because I was tired of looking up information on web sites that required a lot of side scrolling on a small screen. Bigger screens and higher DPI made them easier to read.
Then the sites got redesigned using newer frameworks, and now sites require even more side scrolling because of all that f*"**ing padding.
Nowadays I don't care about the size of the phone any more, it's all about battery life and weight.
