Chromebooks are fine for the 80% case like normal PCs but that last 20% is impossible unlike normal PCs. There are certain things that you just cannot do. It is disingenuous to market them as PC alternatives or general purpose computers.
They are merely different and not better
I'm not sure they are ethically acceptable either as they are solely to promote and lock people into google's ecosystem. This is a dangerous line to tread. Vendor lock in has been made socially acceptable now through years of marketing in a typical us vs them fashion. If you're not taking a side, you are an outcast.
And no I don't think installing Ubuntu on them is a good solution either.
I genuinely have nothing positive to say about them. And yes I have owned one.
