We recently downloaded Skype to our computer and opened an account with them. We were hoping to be able to use it to call friends and family whenever we have internet access, rather than using the expensive Ladatel phone cards here (.50/minute to the U.S.). We didn't have too much luck using the wireless internet at Marina Palmira in La Paz, calling from our computer to a landline. Voice transmission was in and out and often the person we called couldn't hear us at all. We know it depends mostly on the amount of bandwidth available, but we're hoping that a computer to computer transmission will work better than calling land (or cell) lines.
So all you friends and family out there - let us know what your experience has been using Skype, and email us your account name so we can try calling you from Barra de Navidad (our next opportunity for internet)!
