You can't stop progress
Things are bound to change, and the move to mobile devices will only accelerate.
As a motorist, however, I am somewhat dismayed. There are enough distracted drivers operating dangerous machinery while their eyes are glued to a cell phone interface or key pad instead of the road. I think that mobile devices are great, but they should be used at appropriate times. My state has been wary about making the use of hand-held devices illegal while driving, but, to me, this is a no-brainer. I would rather share the road with an impaired driver who has his eyes on the road than with a sober driver who's more interested in reading his text messages.
