I’m sometimes shocked at how much my wife relies on and accomplishes through her Pixel 3. She uses a computer only when she wants a bigger screen - photo editing or watching a show. Everything else she uses her phone. Is very surprising to me. I feel like I can barely do anything on my phone.
It depends a lot on how much typing you do. If it's mostly reading, phone is tolerable. For HN or Reddit, I want my damn keyboard.
But, conversely, the way we interact online also changes to accommodate these trends. Twitter was an early example of that, and so is the focus on audiovisual content over text for the more recent social networks.
