Android and iOS have pressure on app developers to support IPv6 or at the very least function on 464XLAT. On home broadband people could connect anything including programs that use literal IPv4 addresses and break on 464XLAT. Things like corporate VPNs, Skype, online gaming. Ironically these services would benefit the most from supporting IPv6 but they've evolved to deal with IPv4 NAT to the extent that they've become dependent on IPv4 connectivity.
