Exactly… modern phones are crazy powerful and would work as desktops for 99% of users if they weren’t locked down in software. I have an older $100 iPhone SE2 and it has more cpu power than many new $1k laptops.
Spot checking this, I don't see any manufacturers making a $1k laptop in the same ballpark. Closest seems to be Dell trying to sell last gen processors for the same price as current gen and those are at least 2.5x faster. Excluding them, everything else was 3.5x faster with some far exceeding that.
That being said, it would probably be enough to service many computing needs and one device is a great deal more convenient than multiple.
