I would love for my phone to be my primary computer, and just plug it into a mouse/keyboard/monitor whenever I need to do real work (the latter implies having full control of anythin I want to control, like I have now in Arch Linux). Other than that, I don't really see the use case (for me personally) for most of what you're saying. I mean, vi/emacs are not useful on the phone, because it doesn't have a real keyboard. Since it doesn't have a real keyboard, I can't do real things with it, so there is no need for a lot of customization (e.g. with dotfiles).
