Earlier quoted context omitted.
I disagree, there's plenty of things I think a small form factor excels at. Do I enjoy using Word on my phone to write a document? No. Do I enjoy writing texts and messages on my phone? Yes. Would I get my laptop out to write a text message or make a call all the time? No. The fact it's portable and can fit in your pocket, is the exact point and I can navigate the entire device with two thumbs.
I'm not entirely sure you disagreed. It sounds like mostly what you value is indeed the portability ("I don't want to get my laptop out"). But the actual experience of writing a text on your laptop is better (at least for me). If I ever need to write a long message or many messages, I do get my laptop out because the hassle of that is outweighed by how much faster I can type on a computer than on my phone.
The fact that I can video call my mother almost anywhere in the world, view emails, send high quality photos to family and see pictures of my friends around the world using two thumbs is hardly a technological regression.
Do I prefer writing emails on my mechanical keyboard looking at my 27" IPS display, yes. But that doesn't take away the value of my mobile phone that allows me to do that anywhere anytime.
