I prefer texting and emailing, use them both about equally. It's become practically the only way I have of communicating with my kids and grandkids.
But we do occasionally use the phone in the old-fashioned way, maybe for birthdays, or if we expect a long, complicated conversation. Most of my friends still prefer phone calls, so I do talk to them on the phone, but with the ones who are younger (or more "with it"), I prefer to text.
Why? Several reasons. Texting is less intrusive, doesn't interrupt people when they are busy, or sleeping, or driving, or whatever. They can answer when it's convenient. For the same reason, I prefer to get texts.
And the telemarketers and scam artists haven't exactly done wonders for using the phone; most of the time, we've learned to ignore it.
Also, by texting, we can reach several, or many, people at a time. My friends and I just arranged to go to a show together by communicating via email. It would have entailed a LOT of phone calls to do it the old-fashioned way. Some technological advances really are improvements.
