Yep, I use one. I commute 100 miles/day and it provides situational awareness for going around accidents plus it has NOAA weather.

Interagency differences in 10-codes is not really a problem here even though I cross 4 different jurisdictions. Even in a strange area one can learn a lot by listening for context.

I consider scanner use to be vital. Your local broadcast news isn't going to advise you of an armed felon fleeing the police in your neighborhood. (for instance)
