Like even a giant iPad with a keyboard isn't productive for me. I just use my phone to check messages, read the news, etc. If I want to do something useful, I just sit down at the ultrawide and use a real OS with like four times the memory.
I played with those folding phones at the store last week and thought to myself "nah, just more shit to break. And what would I do with it anyway? Watch YouTube slightly bigger? It'd be much harder to type on too."
