Since cellphones outnumber PCs more than 3:1 and are rapidly becoming routinely connected to the internet, it is fairly easy to envisage a disruptive innovation that shifts the de facto standard for internet access to the cell phone. A recent UN report reveals that half the globe now pays to use one, with the fastest growth taking place in Africa and a 50 billion investment in broadband networks there. Ok it might take 10 or even 20 years but it's likely to be the future so given that, starting on a free on-line curriculum is a reasonable strategy because that too will take time to develop.
