Huh? Why India? The link talks about Africa. The Indian mobile market has been completely taken over by Android. About 50% of molbile phones sold in India are cheap Chinese phones. But even those these days come with 1Ghz processors and 4 inch screens (albeit of poor quality).

These run Android fine. Firefox OS is at the moment clearly heading for the no-mobile-phones-yet market and offering a low-end phone. India is somewhere in the mostly-mid-range-mobile-phones zone now.
