It's weird that the inventor has it so they don't have to text. About the only thing I don't do on my phone is talk into it. Phone calls are so insistent and immediate, those are the things I want to not do. We can't all only phone out- who would ever answer?
Organisations that don't use the internet effectively, mostly. That's usually why I have to make phone calls. And I tend to avoid doing that from my mobile, because the codec makes it more difficult to hear. At least callcentre monkeys and reception staff are being paid to do it.
But hey, I appreciate the telephone dial as much as any other piece of clever but anachronistic mechanical witchcraft, and building a mobile phone around it is a lovely work of art. Prolonged exposure to nikki OTP has made me appreciate that the art in this case is as much about making people think about how they use mobile communications as it is about the device itself.
That I inevitably come to the conclusion that a mobile phone that can only make voice calls is basically useless
[1] to me is probably fine. Also, other people are not me. Some people find written material difficult, for whatever reason, and are likely to have very different feelings about telephones. Some people are much worse at ignoring non-urgent interruptions.
[1] I mean sure, it's probably worth having, in the sense that a distress beacon is worth having.
