The delay (latency) for satellite communications is almost 1/4 second (240 ms) due to it's distance above the earth. This is if you are sitting on the equator and it is directly overhead. Farther away from the equator and the more the "angle" to the satellite the longer it will take...but it won't add much. The shortest round trip is almost 45,000 miles.
To that 1/4 second round trip delay, you need to add the normal latency of the ground communications at each end.
Not a good choice for any type of interactive activity...like scrolling a web page. Satellite video I've seen is seamless.
