What is the main advantage disadvantage of a satellite broadband Internet connection compared to a regular fixed line broadband connection?

Satellite Broadband has a 3 to 6 second delay, you would notice most in multiplayer games (unplayable) or "Skype" type video "meetings"(huge lag in the conversations). It doesn't have near the speeds that most low end DSL/cable broadband has. It also costs way more to install and the monthly billing is quite high for the low speeds that you get. The only real benefit would be if you could not get a dial up or any DSL/Cable service in your area. You could still use it fine for email, instant messaging, surfing the web and the like.
