I wonder if there will eventually be a "split the difference" option:  Mobile FRS.  If I understand correctly (corrections welcomed 

 ) the FCC allows 
GMRS mobile units  but does not allow 
FRS mobile units.  
IOW, by law all FRS radios are HTs with the mike and antenna attached to the hand-held unit.  There are also power restrictions.  But the advantage of the FRS is that it is (again, I'm going on my recollection here) a VHF frequency FM unit instead of an HF frequency AM system (which is what CB is.) 
EDIT:  Just checked the web, FRS/GMRS is actually UHF (462 - 467 MhZ) not VHF.  
(by "mobile" I mean a radio set that can be permanently mounted in the vehicle with a separate microphone and antenna like a 2m Mobile)
For me, Mobile FRS would be a perfect system:  FM/UHF for better sound quality, and a simple non-repeater (simplex) 'channel' system like CB for ease of use.  
I have to be honest, I'm not a "radio geek" and that's why I let my HAM license expire in 2004 (KB0LOG if anyone's interested.)  Besides the 4x4, I also have a motorcycle, and I like to shoot/hunt. 
 I also have a wife, a dog, a house and a job, all of which occasionally require some of my attention.  

  So the reality is, I just don't have the time for another "hobby" which is what HAM would be to me.  Even 
without the CW requirement (which I passed in 1993, although I couldn't today) HAM requires too much "commitment" and that's not what I need a radio for.  I just need a radio to be able to talk to other people on the trail.  
So I say:  Bring on the decent priced, decently featured Mobile FRS units in the $100 - $200 price range.  Once they catch on and everybody has one, I'd love to have one in my rig.
