A satellite laptop is similar to a satellite phone. It provides the wireless internet connection by linking to a satellite in space. It is useful when you will be in areas with no phone or internet coverage from landlines or wireless towers.
Satellite TV is not for me. It might be if it was available on tablets on the go. Then it would be useful because you can watch television wherever you are.
If that translates as a geosynchronous satellite, then yes it is useful. This is a satellite which, once attaining high orbit, its speed is synchronized to the speed of the earth's orbit. This permits the satellite to remain in the same stationary position over a given portion of the earth's surface. These types of satellites are useful for communications such as weather and television etc. as there is no loss of signal. At least, that's the idea if one discounts a snowstorm or heavy rain and the tv goes out.
