You've done a good and useful overview of the AP+BP architecture, but I 
think you need to rethink describing this as something that 
differentiates a smartphone from a feature phone.

I agree that there's no industry definition of feature phone vs. 
smartphone, but I don't agree with your suggestion that a feature phone 
has just the BP and a smartphone a BP and AP. For me, a feature phone is 
voice calls plus some features (music, camera etc.) and smartphone is 
voice calls and installable native software (i.e. not J2ME). It's a 
marketing difference more than anything.
