For a long time, I struggled with a similar view. The lines for this are blurring very fast though. Example - Amazon's kindle is more or less a single purpose system - but runs linux, lasts for days on battery, has good RAM and a relatively powerful processor.
Great product - Will be really handy in BLE firmware development as well I guess. Somehow I thought this was an implementation of "IPv6 over Bluetooth Smart" though :)
FWIW - India has one of the best money transfer infrastructures [IMPS/NEFT/RTGS]. IMPS is my favourite - it taps into the ATM machine backbone and enables 24x7 instant payments at almost zero cost [ http://en.wikipedia.org/wiki/Immediate_Payment_Service ]. The problem is more than the lack of infrastructure - Most folks are a bit apprehensive about using Cards or Online banking capabilities for fear of theft.
Paid plan for API access I guess - hoping one wont use the same environment for both. I meant this for the stripe frame which kicks in, cant really trust an https frame that has a start from http.
