Larger screen is better for movies, most apps, and especially web browsing!
My Nexus fits in my pockets better than my iPhone does do to being thinner, lighter and having rounded corners.
I totally agree with both of those statements.
A bigger display is great for viewing anything.
In this case, a bigger device actually fits pockets better and is less visible from outside, because it's so thin and light and curved. It just slips into pockets like a knife in a sheath. No shoving needed.
