You make it sound like a bad thing! That's pretty much already where I'm at, and is in fact exactly what I want. My smartphone is for messaging and a handful of apps from major vendors (Google Maps, Youtube, 1Password, etc.) It shouldn't ever crash, have nagging software updates, require tinkering, etc., just like my microwave and washing machine. And for tinkering, I've got my Mac, my little Linux NAS, a variety of Linux handheld devices, etc.
