4G will be almost everywhere with peak speeds often over 100 megabits. 100 megabits will be slow for wired connections in the developed world. Most developing countries - except China - have very few landlines and it's not clear wireless will have enough capacity for much video over the net. Prices in strongly competitive markets will be flat to down because the costs of modems, Internet transit, and nearly everything else are going down. In the more common weakly competitive market, like the U.S., prices will creep up unless the regulator is strong.
Two billion more people will be connected to the net as LTE phones drop under $50. Africa will have more Internet connections than the United States by 2017, more than the 315M population of the U.S. India is growing almost as fast, and China already has twice as many connected as either the U.S. or Europe. The rich countries are today 40-45% of connections; by 2019, that will be down to 35-40%. 5% to 25% of homes will be screwed as rural areas have limited coverage and competition.
