I can't find the link now, but I remember some discussion of cheap Chinese-made Android phones selling for single-digit numbers of dollars. At the end of the day, it's just like any other piece of electronics. It's not like Android phones are made out of more expensive raw materials than dumbphones. They're just newer. So I think that eventually the third world will be swimming in smartphones-- probably a lot sooner than you think. Whether or not that impacts your business model depends on what the business model is, of course. I'm sure a few more Symbian apps will be cranked out as retailers blow out their stock of old inventory. Very poor people will probably hold on to old phones for years, as well. But phones do break, and batteries die after a few years, so a decade from now Symbian will be just an obscure memory, like the Acorn Archimedes or the ZX Spectrum.
