You're just making up your own definition of "computer" and then claiming a smartphone isn't one because it doesn't match your made up definition.
You have programs, you have a UI to control them, they have a CPU and memory.
Otherwise everything is a computer.
Maybe cut to the chase: what specific capability is an iPhone lacking that every “real computer” has?
It's possible that I could be somewhat productive on a tablet in an emergency, but not as my main machine like Apple suggest people should do.
I have tried using an iPad Pro for productivity, and it's living hell.
Wouldn’t that mean most servers aren’t computers? Not to mention the DOS machines I grew up with, or everything made before the Xerox Alto?

Not going to disagree with you there. But that doesn’t make it not-a-computer.
If we want to classify devices, we need to group them somehow. Otherwise we call them devices and call it a day.
We already classify them: smartphones, tablets, laptops, desktops, servers are all groups of computers.
At that point, you're running a mouse-centric, multi-window OS with a wide array of software, that can run basically whatever you want.
So that's a computer, definitely, right? When does it stop being a computer? If you disconnect the display? Is it using a stylus instead of a mouse? Maybe the software keyboard instead of a hardware keyboard? (But then is the MS Surface not a computer when you detach the keyboard case?)
That said, I still think smartphones qualify as computers even by your productivity definition. Newer smartphones would sit somewhere above older netbooks on a ranking of overall utility.
Smartphones are capable of computing and are sometimes very powerful, but the analogy is totally out of wack in my opinion.
If you can live without using an actual computer, it means you don't really need computers. You can check your email and browser the web on a Kindle, on your TV, or even your car.
Everything is a computer, then.
I think a computer is a productivity tool. Smartphones (and I'd definitely say tablets, too) are to consume content, not produce it. Some companies (most notably Apple I think) believe otherwise, but I think they'll have to come to realize that smartphones and tablets are horrible to produce most kinds of content.
