If you've never used a larger-screened phone, you may not see the benefits immediately. I went from a 4s to a Lumia 1020. Initially, I thought it was way too big, but the supple, thick, curved edges and ergonomic design of the 1020's case made it much easier to hold and I acclimated quickly. Going back to a 4s seems quaint and stupidly tiny now.

This is progress. Either get with the times or get left behind. Use cases for mobile devices have completely changed, and now there are serious, tangible benefits to a large screened device that no one except an extreme minority is protesting. Note that this doesn't mean they all have to be tablet-sized; anywhere from 4 - 5" is what most would agree on as the perfect range for devices. The iPhone 5s/c isn't even 4". It's 3.997" if we want to be pedantic, which is too small for everything we use smartphones for now.
