The nicest to hold iPhone ever made was iPhone 5. I'm sure it was his favorite.

The first time I held an iPhone 5, I thought it was a demo device. It was too light to actually be the real device. That was such a great phone.

The iPhone 5 size was designed for people who use smartphones a healthy amount, ie not very much, usually in pocket and often one-handed for a small task. At some point, that was no longer how smartphones were most often used.

I kept my 5S as long as possible, until my carrier wouldn't even provide cell service to it.

And it sat perfectly flat and didn't wobble when you set it down... ¯\_(ツ)_/
