The last family i lived for a week got internet access from a friend who got those coupons. So, from what i was told, basically people that need to have access to the internet at work get a sort of coupons for some hours of internet usage and there of course there's something like a black market for it. Anyway, i don't think peoplein Cuba miss Facebook. They'd probably be more then happy to have mobile phones in general and a good mobile/GPRS coverage for now. In general, internet is so extremely slow over there that it feels like the whole country is on an analog line from Fidels office.
