Well I had the displeasure of having to use a candybar style phone my mother was using cause it was ‘easier’ for her.

• Ages to write a message
• Very difficult to navigate through very similar SMSs (automated ones like electronic prescriptions) and pick the correct one based on date. Or even get an accurate broader picture of how many SMSs you received and when.
• Did not setup email but I believe it would also be horrendous

But in my case, I disagree with the base premise of this post. The biggest anxiety and distraction caused by my phone is via phone calls. Asynchronous communications like sms and email are much better for me.
