I honestly have to strongly disagree with that. Desktop Linux is more complex, more fragile, and more choice-less than 10-15 years ago. It might have a bit better hardware compatibility... but even back then it would run on just about anything.

But can you actually use them as a phone? Can you use all (or even any) of the apps that people want to use?

Without that, they'll also never get the things that people want their phones to do.
