My phone is an appliance and I'm perfectly fine with that. I dread owning another computer I have the responsibility of maintaining. We are drowning in "computers" these days.
These things are not general purpose computers. They are custom fabbed hardware with vendor supported software and are not user repairable. They do one job and they do it well. At the end of their service life you replace them.
My iPhone is an appliance and I prefer it that way.
