A Firefox smartphone for a developing world may be one small step to cost effective smartphones, however, the ultimate prize will be to get WebOS open source out of beta and in the hands of cost effective, even small country, government subsidized, hardware vendors to mass produce the devices.  The question remains, will Firefox be expandable enough, yet energy efficient, and will WebOS be energy efficient.  I hope HP designs a ‘lightweight/energy’ option into the phone.
