I am, but that hardly makes a difference. Assuming households residents amount are spread randomly between household with computers and households without then the ratio holds for individuals(the assumption is probably slightly off, since there is likely a correlation between poverty and having a computer and poverty and number of children, but I doubt it's very big and besides the same correlation most likely holds between poverty and having iPhones) And the iPhone was released in 2007, not 1997.
