> Operating systems should be modular, allowing the user to reduce as much bloating complexity as possible and needed.

Yup, updated my comment to clarify that point -- thank you. "the overthrow of the root user by the corporation" -- damn. Good turn of phrase :-(

If the sealed system makes performance or security problems, it's a bad design, I'd rather it be optimized rather than modularized.

Modular systems have more possibilities, which means some of those possibilities might not work, and then you might find yourself unable to use an app without reconfiguring in a way that breaks some other app.

They are great for tinkerers and specialized applications, but for people who want things to Just Work, every time, no matter what, even at the cost of zero hacker friendliness, Android's model seems to completely blow Linux away.

We should still have root(I think lack of that might be part of why Android hasn't started taking over other markets), but there should be obvious and standard ways to do common things.

>The commercial OSes aren't perfect, but they are popular with consumers for a reason.

I don't think it's clear that those reasons have much to do with any property of the OSes though.
