Exactly. Cell phones are cheap and nigh-disposable. Hell, you can get one at 7-11 (AM-PM for you west coast people). An expensive device -- a palmtop computer, say -- should not have a cell phone built in, because when the cell phone dies, or you you change cell phone providers, then where are you? Carrying a separate cell phone anyway, and your palmtop is bigger than it needs to be because it has a now-useless cell phone built in. Cheap, bulky, disposable things should not be built into small, long-lasting, expensive things.
