From what I have read data speeds are slow (2.4Kbps). which is slightly better than dialup. I would not expect a fluid response with bandwidth thirsty apps like netflix, youtube, facebook, etc.... (I wouldn't expect such apps to be usable on such a slow connection)

Although data speeds are reportedly to increase (1.5Mbps) when Iridium "Next" rolls out in 2015 (according to Iridium). 1.5Mbps is still significantly slower than broadband connections of ten years ago but could pass as acceptable in a wilderness setting.
