I love this idea with one caveat: I'd like my phone to almost always be dumb but still allow me to stream music. Since it immediately crashes on my N4 (CM11-M7), I don't know what will and won't do. Presumably though, making a phone "dumb" would me merely a matter of disabling cellular data and turning off wireless networkwing.
