So, regarding equipment (in a purely hypothetical sense, of course):
If someone were to want a smartphone, how would I put that together? I don't think a regular cell phone would cut it, as a base. Would it be better to start with the PDA (assuming full keypad and internet access), just labeled as a smartphone? Would one need to 'purchase' a digital camera and GPS receiver as separate individual items, or could they be tacked on to the PDA/smartphone, since it has the highest initial DC (maybe +1 to the DC for each)?
