I second the multi-monitior comment. I absolutely love my fold and I think that’s a great analogy.
It’s hard to say it’s worth the money though. I personally think it is, but I wouldn’t recommend most people spend $1500+ on a phone in general unless they have a really specific use case.
I suspect you don’t have kids? Most schools require a laptop (usually Chromebooks). What do you do then other than parental controls?
