David Muir quotes:

[Barack Obama] is aware of the criticism back home [from Cuba] that this embargo still exists.

Here in Havana where families make about $20 a month, fewer than 5 percent have Internet in their homes, they are prepared. But it's hard to predict how sweeping this change will be, if the people of Cuba are even ready for it.

I think there [on Cuba] is going to be an extraordinary reception.Cubans are - they want to hold onto their culture, their heritage, but they also want to embrace this opportunity, perhaps, for new economic freedoms.
