On something of a side note, this discussion prompted me to look for a
scanner app for my Droid (had it about two weeks) and lo there was one (well
reviewed, and free). Interesting given the wildfires around here now.
As for the CB, someone is developing an app with that kind of functionality,
although I don't really see them tying into actual CBs (but who knows).

We talk a lot about these different devices in our vans, and I wonder that
these phones/devices won't eventually replace most or all of them. We had
the phone hooked up to the stereo for the music, and it faded it down, the
GPS app gave some directions and then faded the music back up, all while my
wife was refilling her prescription online. Then she looked up the elevation
of Mt. Fuji 'cause my daughter was curious about it since I climbed it once
(but had forgotten the number).

I realize that the lack of coverage in the backcountry is an issue,
particularly for a lot of this crowd (for whom "backcountry" has a different
meaning), but that will presumably change as time goes on. These things are
game changers in many areas in the same way that Tivos/DVRs are game
changers in the way one uses television. I've hardly used my computer
lately; I have to remind myself to sync it up every day.

I can see somebody developing a bluetooth ECU scanner so your phone can
monitor your engine. Why not?
