I mean that seriously, nobody in any of my social circles uses whatsapp. I honestly don't have a solid grasp on who exactly their core market is.
and anyway none of what you said addresses the above reasons for wanting an internet based messaging system

I'm guessing it's whoever was using blackberry messenger.
Admittedly no, but aren't most children on their parent's cellphone plans?
I would expect the cash strapped ones to be in their early twenties, but I'm not seeing that in practice.
I suspect the value in whatsapp is in something other than limitations of SMS, but I can't say what.
Some countries have better plans than others. And teens can send insane amounts of texts.
