I bet Steve Jobs has an image like this in his office.
China would be a big market to enter, but notice the lack of penetration in Africa. I assume the market just isn’t there. The One Laptop per Child Project aimed to bring low-cost CPU’s to the developing world. Perhaps the netbook (or even the iPhone?) is the more realistic device for emerging markets. The idealist in me wants to see Africa fully wired and surfing the web, hence improving the quality of life. But the pragmatist knows that there are many challenges to doing so.
