I find the iPhone has plenty of power for a compact hanheld computer.
“they are millions of times more powerful than all of NASAs combined computing in 1969.

So, it depends upon what the computer was used for in the first place.

It does but I wouldn’t write a book, article, or legal document on it.
I wouldn’t do photo retouching for print exhibition or print advertising (even for a local concert or yardsale) on it.
I wouldn’t do spreadsheet calculations on my phone.
etc.
So if someone doesn’t use their computer to do their job (daytime or outside income), a phone may give them all the computing power they need (calculator, internet, stock quotes, weather forecast, limited movie viewing, games, and communication).
