I've been playing with a Note 3 for a couple days now. It's amazing to me how a few years ago when I saw a 5 inch device I laughed when I saw people holding it in their hands. Now I pick one up and I'm like "eh, this isn't so bad".
Everything is just getting bigger and bigger.
Still too big for me, but definitely see how it's very manageable for those who prefer the larger size.
