> I miss the days of the old tiny flip phones
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.
In some areas. I'll tell you what: my "old tiny flip phone" never froze up, refusing to make phone calls, end phone calls, or respond to user input at all. That's pretty important when you really need to make a fucking phone call.
