Yeah I don't want the only distribution model to be an App Store. And I don't want to lose the ability to run things with root access.

But I strongly believe that right now apps get too much access by default (read, write all my files is crazy). And if they need anything beyond that they just ask for root. There needs to be much more granular permissions, with more restrictive defaults and nice informative dialogs.

It's unsexy, and inconvenient for developers. But it's the right thing for our users. It's how I want random programs downloaded from the internet to behave.
